2020 Last Hundred Days

Project Description

Today (Wednesday 23rd September 2020) is the first of the last 100 days of the year. That is, to achieve a 100 day streak in 2020 one needs to start today. I find this arbitrary allotment of time a motivating opportunity to build new and better habits; it is a race to create change before the year is out. I also think sharing the process publicly will help me keep more accountable. Here are the habits I aim to build (and break) by the end of 2020.

The List

  • Exercise to start the day
  • Sweat for at least 10 minutes
  • Work on mobility and flexibility too
  • Practice meditation
  • Avoid consuming junk content
  • Avoid consuming junk food
  • Achieve “Inbox Zero”
  • End the day by reading a (physical) book
  • Avoid eating in the middle of the night

Health and Fitness

It seems universal that people want to improve their health, but almost equally common that people’s habits don’t perfectly align with that desire. I am trying to correct that cognitive dissonance in myself.

Start the day with exercise; I know days where the first thing I do is exercise go better than days when I don’t, but it’s not an ingrained habit yet to train first thing in the morning. Exercise every day as consistency beats intensity. Gentle recovery work outs are better than nothing at all. Additionally the physical and mental improvements from regular exercise are felt almost immediately. I want to focus on consistent flexibility and mobility work, i.e. stretching (static and dynamic) and foam rolling every day. When I do this regularly my strength and fitness improves. When I stop I get injured.

For me, meditation primarily builds awareness. From this awareness, I can make better decisions and know what the state of my mental health actually is. Practicing mindfulness and meditation also leads to calmer, more focused days.

I generally eat well, but my worst food habit is waking in the small hours of the morning and eating a bowl of porridge oats or a tub of leftovers. Whilst occasionally a 150 g serve of oats at 2 am can be helpful (e.g. the morning of a long run) it is currently unnecessary extra fuel. Usually the midnight snack is not followed by appropriate dental hygiene either, so increasing my risk of dental issues.
Some foods are simply not good nutrition (e.g. potato chips, doughnuts). I aim to shift these from being “sometimes” foods to being “never” foods.

Content Consumption

My thoughts reflect the content I consume, and so improving that content should improve my thinking. For improving sleep, taking the time to read a physical book as the last event of the day avoids the physical effects of backlit monitors, and provides more focused content free of attention grabbing digital distractions. Those distractions I could do without more generally: Reddit provides the anonymous opinions that I don’t actually need to read. Chess is mostly an escape from stressful thoughts where I should action the issue at heart. Shopping websites pit my simple mind against elegantly a/b tested marketing research, and I could be less consumerist. Pornography is stimulating, but can be desensitising.

Productivity and Personal Development

Get more organised to get more (hopefully good) done. “Zero Inbox” is the one habit I’ve already failed on the first day, but it is an ideal I am working towards. Action or deliberately postpone everything in my inbox at the end of the day.

Personal reflection is a habit I have mostly developed, but could improve the consistency of. I can guide my own personal growth by taking some time at the end of each day to reflect on the events of the day, what I did well, what I could have done better, what I learned, and what I need to focus on in the days to come.

Alternative Ideas

These habits are not on my list for the last 100 days, but if you are inspired to try achieving a similar 100 day streak, these are the first few I would recommend:

– Don’t smoke cigarettes: probably the best thing a typical person can do for their health
– More generally, avoid abusing substances, including alcohol
– Follow your doctor’s instructions regarding prescribed medication (seems obvious but actually is a significant issue in health care)
– Stop eating meat: a significant improvement to impact on land use and climate, with some possible health benefits
– Decrease expenditure below income: simple financial management

2020 Week 35: The Faintest Ink

This week I’m sharing a quote, a tweet, and a library.

Quote I’m Pondering

The faintest ink is more powerful than the strongest memory.

Human memory is fallible, where written notes do not forget. The quote encourages note taking, but implementing that lesson is not trivial. As the exercise of observing a candle can demonstrate, a common occurrence can give rise to tens of distinct observations. Time is finite, and so is the detail in which notes can be taken. I tend to take comprehensive notes inconsistently, which suggests that I attempt an unsustainable level of detail. Ultimately the value of memory or note taking to a situation that has not yet occurred is unknown.

Problems in Science

Science can seem apolitical from the outside, it is often perceived as a rational and collaborative exercise in furthering understanding of the natural world. In reality humans, their endeavours, and the systems they build to achieve them, are all flawed. The incentives of academic research prioritise production of highly cited research papers, creating races to publish ideas first, which ultimately stifles collaboration and sharing. This tweet shares the story of an observation stolen by a visiting professor. The subsequent conversation between scientists in the thread reveals a nasty and paranoid reality of scientific research.

YC Startup Library

A problem I have written about is that the amount of content I can access vastly exceeds my capacity to consume it. The YC Startup Library offers curated resources on startups, and a more efficient way to learn about entrepreneurship than the YouTube suggestion algorithm.

Extreme Ownership

Reading Notes

Extreme Ownership by Jocko Willink and Leif Babin uses experiences from their military career (primarily during the Iraq War) to describe principles of leadership. I found the book helpful, particularly as it addressed several weaknesses I see in myself. Both in war and business, the contexts used to describe implementing the principles were higher stakes and more challenging than the situations I find myself in, so I feel the solutions offered would also help solve my problems. Since encountering Jocko’s philosophy via his podcast over a year ago, I feel implementing the ideas in Extreme Ownership have helped me to grow and succeed.

The military content, which makes up a majority of the text, at times glorifies war and some readers will find it distasteful. I would suggest simply reading and considering the core principles, which together make up approximately 30 pages of the 320 page book. The 12 chapters each follow a structure of: 1. military anecdote 2. leadership principle 3. application to business. I found these anecdotes illuminating. In the first chapter, where Jocko describes taking ownership of mistakes leading to a death by friendly fire, he writes “I dreaded opening and answering the inevitable e-mail inquiries about what had transpired. I wished I had died out on the battlefield. I felt that I deserved it.” Even within the intense environment of war, something as common as email can cause “dread” because of the courage required to take ownership of mistakes. The example uses the dire consequences of war to motivate me to take ownership of my own mistakes.

The Principle of Extreme Ownership

Everything that happens to you is your responsibility. Do not make excuses. Do not blame others. Inevitably things will go wrong, and you will fail, but taking ownership can lead to learning, growth, and overcoming that failure. Making excuses, and blaming others, prevents growth and leads to more failure.

I find this a useful mindset. I have much more control over my own actions than others. I can choose what I do, but not what others do. If I externalise control to the world or others around me, and blame the world and others, then I am unable to solve my problems. If I focus on what I can do, on what I can control, then I can make progress.

Quotes I Found Helpful

Note: I hope to add more quotes and expand on these quotes later.

Every leader and every team at some point of time will fail and must confront that failure (p. 8)

This is consolation, failure is to be expected rather than feared. Failure does not mean an individual or team cannot ever succeed. Knowing this, it is possible to move past the embarrassment of one’s failure, and focus on how to improve and overcome.

It’s not what you preach, it’s what you tolerate. (p. 54)

Standards are set and maintained through tolerance. While an individual or team can have lofty aspirations, consistent performance requires intolerance of sub-standard behaviour. In short: Hold the line.

Relax, look around, make a call (p. 161)

Mantras like this help the right decision be made in difficult situations. This needs to be balanced with hesitation, which can be more damaging than haste. Relax: take a deep breath, move past the adrenaline and the pounding heart, clear your thoughts. Look around: detach, take in the bigger picture, understand the context of the situation, what is actually happening here. Make a call: once the situation is understood and a pause can be taken, only then make a decision.

2020 Week 33: Target vs. Direction

Over the last few weeks I’ve been focusing on process, rather than outcome. Optimising my routine and input to work, especially when the output of that work is inherently probabilistic, avoids the emotional rush and crash of success and failure.

In order to optimise, I like to collect data. I measure how long it takes me to perform tasks throughout the day, which approaches succeed more often, which channels and sources are more fruitful. That optimisation, though generally useful, can become a distraction. When I become more upset at a failure to collect data than a failure to deliver an outcome, it is a sign I have lost focus.

In noticing this, while keeping track and optimising are important, that cannot replace awareness of the actual desired outcome. Do not let excitement about tools and processes distract from the simple question: am I getting closer to my goal?

James Clear Questions

I’ve started answering the questions James Clear asks in his weekly newsletter on a page. It is incomplete, but I am nudging myself to write content separate from this weekly post.

2020 Week 32: Ownership and Plots

I’m thankful that my physical and mental health are good. Time spent around writing leads me to explore interesting ideas, but the actual output (this post) is relatively unsatisfying. Maintaining the habit of posting weekly feels important though, so as usual, some partially refined ideas:

Taking Ownership

I was reminded to take ownership of certain projects this week. It is advice I am primed to hear, but even having accepted it, the actions needed are not trivial. It requires overcoming ego, as Jocko describes in an early chapter of Extreme Ownership. The idea, also presented in the quote below, implies a certain arrogance, but I feel it can be accomplished with humility.

There is only one means of salvation, then take yourself and make yourself responsible for all men’s sins, that is the truth, you know, friends, for as soon as you sincerely make yourself responsible for everything and for all men, you will see at once that it is really so, and that you are to blame for every one and for all things.”

The Brothers Karamazov by Fyodor Dostoyevsky

On the topic of ego; this heartwarming 51 second video from Clay Tall Stories also points out how ego can be dangerous. I hope that content like this can defeat the stigma of talking about mental health that exists in so many parts of the world.

Thoughts Better Expressed as Charts

A joy of studying and thinking mathematically is that functions (easily visualised as plots or charts) express relationships. By identifying functions that approximate (model) real world experiences, an optimal outcome can be predicted. I describe two examples that came up this week.

Discontinuity: Sudden Drop Offs

One of the most familiar relationships is the straight line, linearity. If we travel at a fixed speed (e.g. our walking speed) going twice as far takes twice as long, and three times as far takes us three times as long. If we are moving bricks, the more time we spend moving them the more bricks we shift. Sometimes though, there is a discontinuity, a sudden change in output.

Examples (Be wary of the discontinuities in life):
1. If we consider the example of moving bricks, the more bricks we carry per trip, the faster we move them, until the load becomes too heavy to move and we are stuck.
2. I can read so many articles per day, but after a certain point I no longer am able to remember what I am reading.
3. I can physically train so many hours, but after a certain point over-training leads to injury and I would have been better not doing any at all.

Linear Expectations Meet Logarithmic Reality

Because linearity is common and familiar, it can become an expectation, but in fact often each additional amount of effort or cost spent may offer less and less. Notably in the plot above, if linearity is the expectation, and the actual relationship is logarithmic, the difference (expectation – reality = disappointment) increases approximately linearly.

The first book I read on a topic gives me a lot of information, but each additional book has more and more overlap with content I have already consumed. This means that even though the trend is to know an area of knowledge better, I learn less and less with each subsequent hour spent reading. If I expect to continue learning as rapidly as in those initial hours, days, or months as in the subsequent ones, I will be disappointed.

Predictions on Remote Working in 2001 from 1976

I am trying to better apply hypothesis testing to my own life, so it is amusing to see the predictions made 44 years ago around remote work and computing knowing how there has been a rapid acceleration in 2020 due to the pandemic.

2020 Week 30: Backup your Data

Friendly reminder: is your data backed up? Maybe you want to check on that.

This week I had the satisfying experience of automating a tedious task and saving myself time by generating reports via Google’s Apps Script. As I am more reliant on cloud services like Google Docs, OneDrive, and Strava, the news this week that Garmin was hit by a ransomware attack is a good reminder to maintain local backups.

News: Garmin hit by Evil Corp’s WastedLocker

Garmin, maker of a wide variety of GPS related products, has experienced a significant outage this week, which is ongoing at the time of writing. Bleeping Computer reports this is due to a criminal attack holding Garmin’s data to ransom for $10 million. Given Strava recently has been taking criticism from users due to pushing people towards paid subscriptions, Garmin’s trouble here is likely to benefit Strava. It also serves as a reminder to all of us to maintain good back ups of valuable data, and to be wary of single points of failure when there are malicious actors in the world (as well equally damaging benevolent incompetence). Meanwhile I’m going back to manual uploads.

2020 Week 15: Growth amid Crisis

This has been another week of excitement, exhilaration, and exhaustion while working on SARS-CoV-2 projects at ONI. Doing experiments directly related to the pandemic is motivating, and I have noted that I find it easier to work 80-100 hour weeks on this project than 60-70 hours weeks on previous projects. I am very thankful to work with such an inspiring team, as well as to live with supportive friends. In the fourth week of this project, the sustained effort is also made possible by prioritising good diet, regular exercise, and making time for reflection and meditation.

While my week is dominated by the pandemic, I’ll share three moments unrelated to COVID-19. As I was drafting this post, I had a failure of discipline and did not get it out on time. I shared my new job title on LinkedIn. I attended an online interactive performance of The Tempest.

Practise Finishing or Practise Failing

The problem:
This post is a day late. I am disappointed, having managed to deliver on time for the past several weeks, and I felt the resulting introspection was worth sharing. I had enough time to write when I returned home on Sunday evening, but found myself falling into bad habits of procrastination I had hoped were gone. Surprisingly, the lack of resolve came not after a day of exhaustion, but one of relaxation. A day of Easter feasting, an absence of physical training, and only minimal experimental accomplishments left me lacking confidence to express my thoughts. When I could have been writing, I squandered time to distractions like YouTube and chess, sacrificing both a timely post and precious sleep.

A potential solution:
I have noticed a psychological benefit from completing 30-60 minutes of intensive indoor rowing. There are several points (usually at around 7 minutes and 20 minutes in) during these efforts where the temptation is to give up and stop rowing. The spartan rhythm of the exercise, and the absence of visual stimulation, are a backdrop for a battle between falling to weakness of will or building strength of discipline. I have found that days where I see the piece to the end, I am not only rewarded with exercise-induced endorphins and the satisfaction of completing the session, but also I find it is easier to see other tasks in my day to completion. Likewise, if I quit before finishing, it makes failing other tasks more likely. Either practising pushing through pain, or practising giving up when things are hard, reinforces the behaviour. Knowing this, I can focus on succeeding in the present moment, spurred on by recognising it will make the right choice easier in future. This knowledge also feeds into setting appropriate goals: goals which are impossible guarantee falling into a negative feedback loop.

Where else I want to apply this:
There are many brief moments through the day when I could learn a little, or train a little, or communicate better, or help someone. Sometimes I make the right choice, but often I throw that moment away in favour of consuming easy content (e.g. checking sales at an online store) or narcissistically checking for “likes” on social media. I should recognise that by building better habits around these moments, I will find it easier to do the better things. A little discomfort now is worth the behavioural change in the end.

People Growth Engineer

This week I announced my new job title as “People Growth Engineer”. Given the current pandemic related work, I am still applying my skills in the laboratory, but eventually the role will see me focus on the people of ONI rather than wet bench experiments. I am excited at the opportunity to contribute in a new way, driving growth throughout the organisation. I like that the unique title reflects my own passion for a scientific approach to continual learning and personal development. Specifically, the growth I will be engineering for ONI exists in three overlapping areas:
1. Growing the team through identifying the right people to join ONI.
2. Growing existing ONIees (ONIemployees) through individual skill development.
3. Cultivating a culture and fostering a common mindset that allow us to achieve our mission.
More detail to come as I transition into the role.

The Tempest

Over the long weekend I attended Creation Theatre’s performance of The Tempest via Zoom. I thoroughly enjoyed the interaction with the audience and actors, and the fun retelling through modern technology. Initially I was sceptical about setting aside time in this busy period for a play, but the life and laughter I took away from it gave me more joy than I would have expected from any other down-time. The actors involved the audience as Ariel’s spirits, acting out Prospero’s magic. Seeing other audience members on their web-cameras provided a good substitute for in person socialising in this time of social distancing. The humour could be a little cringe worthy at times, but taking Shakespeare playfully feels both authentic to the spirit of the comedy and makes supposedly high culture more accessible.

2020 Week 7: Curfew

This week, in several situations, I ran out of time. By not setting end times for experiments, training sessions, or social occasions, I find myself realising on reflection that I regularly continue longer than would have been optimal. Of course the future is unknown, but making an estimate of how much time I ought to spend before I start, and then evaluating the situation once that time has elapsed, should help me to fit more into each day. This week’s longer post on productivity is highly relevant.

Things I wrote this week

I finished a set of thoughts on how to get more life into the fixed amount of time each day, i.e. productivity. Eventually I’ll reorganise the homepage of this website to have pages dedicated to a few significant topics, and I suspect productivity will be one of them.

Things to share this week

Atmospheric Optics collates visual phenomena that occur due to the spontaneous formation of optical systems in the sky, a common example being rainbows. Thinking about ice halos reminds me of X-ray crystallography, perhaps the most famous example being Photo 51.

Emma Stoye of Nature collated scientific photos from January, including the tracks from the head-crab like robots I shared a couple weeks ago.

The UK brought forward its ban on cars that burn hydrocarbons to 2035, some good news for the climate. I suspect unrelatedly, Telsa shares broke $1000 (and continue to be the centre of reddit shenanigans).

Artist Simon Weckert walked around with a cart full of smartphones to trick google maps into plotting non-existent traffic jams. Whilst I find google maps traffic useful on the rare occasions when I drive, I find the “performance” of having a bright red cart full of smartphones intruding into live updating maps a cute reminder of the difference between reality and abstractions.

Productivity Update February 2020


I want to get more done. I constantly have unfinished to-do lists and projects I would like to take on, if only I had more time. Rather than simply aspiring to have more time (e.g. by living longer), it is equally valuable to do more living in the time I have. I see increasing productivity as converting time I feel is wasted into time I feel is useful, by either decreasing the time useful tasks take or removing tasks that are not useful. This post is a collection of things I have found to help with this, and areas where I am seeking to improve.

Things that I think work

Prioritise health

If I am mentally or physically unwell, my productivity rapidly decreases. Keep health as a priority. Assess it regularly, and take time to eat well, exercise, and sleep. Follow good hygiene practices. When ill, make recovery the single highest priority.

Hesitate less

Increasing productivity and focus first require that you actually start doing something productive. Whatever that is, learning, training, meeting people, or something else, I often find myself hesitating to start. Fears of failure may be reasonable or unreasonable, but not starting at all makes failure a certainty. Of course some projects are more risky; the costs are higher, the harms can be bigger, but generally the first few steps don’t require such a big commitment, and having started I will be in a better place to assess what can be done. Simply put, just start.

Solve what you need to do, not what is easy to do

The blue areas (important with known solutions and unimportant with unknown solutions) take care of themselves; things that are important and easy to do get done with much satisfaction and hard things not worth doing don’t ever get started. The trick is doing the important things that don’t have solutions yet. They’re so hard! It is frustrating to try and fail, and failure is likely since the solutions are unknown. It is much more attractive just keep working in my comfort zone of known solutions, even if they are unimportant at least they are easy. The more time I shift along the yellow arrow, the more productive I am.

Focus on what is important, and do not be distracted by what is easy. I think most people are familiar with a time when, rather than write a difficult essay, or make a difficult phone call, suddenly they were inspired to reorganise their desk or tidy their house (Tim Urban goes more into procrastination in this TED talk). I’ve lately been thinking about it in terms of the diagram above; trying to focus my attention away from the easy but unproductive tasks and towards harder but more useful tasks. A related concept comes from an anecdote about Warren Buffett advising Mike Flint about goal setting.

Example – Science
Easy Productive: Setting up experiment
Hard Productive: Interpreting experimental results
Easy Unproductive: Selecting nice colours for charts and plots
Hard Unproductive: Writing new spreadsheet software

Example – Writing
Easy Productive: Choosing a topic to write about
Hard Productive: Actually writing about the topic
Easy Unproductive: Selecting fonts, organising stationary
Hard Unproductive: Writing in an unknown language

Example – Fitness
Easy Productive: Signing up for a gym membership
Hard Productive: Actually using the gym membership
Easy Unproductive: Watching YouTube videos about how to exercise
Hard Unproductive: Making YouTube videos about how to exercise

Use technology effectively

Tim Ferris shared this article about how to use your iPhone productively. I was a little underwhelmed by the focus on apps and content to consume, rather than actual phone tweaks that help avoid distractions. Smart phones are powerful devices that can be highly detrimental for productivity. While I am certainly more productive with a suite of tools in my pocket at all times, I can also be distracted by the similarly immense collection of toys. Armies of clever people work to increase the amount of time users spend in their app or on their website, and they are often successful. Some things I have found useful:

Make your phone binary. Either it is a “toy” used for relaxation and entertainment or it is a “tool” to help you work more effectively. If it is a toy you don’t need it with you when you are working. If it is a tool then don’t install games or use it to browse content where the main purpose is to be entertained.

Put your phone in black and white. Screen technology creates images more vivid, and therefore more captivating, than reality. For the majority of useful functions, a phone doesn’t need a colour screen. Putting it in black and white makes it less attention grabbing.

Do one task at a time. Build a habit of telling yourself what task you are picking up your phone to perform, performing it, and putting the phone away again. Sending that text message doesn’t need to lead to browsing Instagram. Checking the bus timetable doesn’t need to lead to reading a news article.

Turn your phone off. When you don’t need your phone, turn it off. Notice how often you pick it up and stare at a blank screen, and put it back into your pocket. If what you need to do isn’t worth waiting a few seconds for the phone to start up, it probably isn’t worth doing at all.

Avoid vanity

Time spent checking social media is not particularly useful, but time spent looking at your own content is especially not useful. I learned that in the early days of LinkedIn, 25-35% of clicks were people looking at their own profile. The speculated reason for this, with some evidence, is vanity. I can certainly feel the urge to check posts for likes, retweets, kudos, etc. It is validating to have people consume your content and approve it. It is also not worth checking repeatedly. The few minutes many times a day adds up to a meaningful amount, the interruption disrupts flow, and the emotions (envy, insecurity, and even the validation from being “liked”) are broadly negative.

Multitask appropriately

Multitasking in some situations can boost productivity, and in others just slow things down. Learn what tasks go well together for you, and which ones shouldn’t go together. I am sure this varies significantly

An example of good multitasking:
Listening to the news while doing steady state exercising. Not every training session should be hard, often I have less intense, putting-in-the-miles work outs. This is a great time to catch up on news.

An example of bad multitasking:
Listening to music while writing. I enjoy it, but changes in songs, and particularly interesting lyrics, tend more often to disrupt my train of thought than to drown out distractions.

Define “possible” honestly

Motivation matters. Setting the bar too high for what level of productivity I want to achieve, or putting too many things on a to-do list, leads to failure, and that failure can sap away confidence and motivation to do more. Be realistic with what can be achieved, keep the ego in check, and when things become overwhelming take time to pause, cut back, and start again with a lighter load.

Things I haven’t worked out

Consume content carefully

I read slowly, and I suspect inefficiently. There is so much content being produced at such an incredible rate, I find myself “tab hoarding”, filling hard drives with PDFs, trying to skim academic papers that I forget immediately, and buying books faster than I finish them. I think the problem is needing to be selective, and to learn to not be “completionist” in my reading, but rather focus on finding things that sit comfortably in my Zone of Proximal Development, and skipping things in a text that I already know, or are well beyond my grasp.

Keep in touch

I am still not good at keeping in touch with friends. I lose time I could be using to catch up with them (via a plethora of communication platforms) fretting about how much I have failed to meet my own expectations on frequency of correspondence. I suppose this is because I am not good at selecting which relationships I ought to prioritise, and effectively let random encounters define which people I spend time with. In not wanting to leave anyone out, I leave everyone out.

Long term goals

Finally, and most challenging to me, finding a major goal to unify my interests, my work, and my hobbies, so that the whole can be greater than the sum of the parts. I lack direction, and this means that many projects I begin and abandon which might not otherwise have been wastes of time, become so.

2020 Week 5: Mountain Motivation

Week 5 sees the end of January 2020, and momentum building both in work and play as I accelerate away from the holiday season. I have been reminded in multiple ways that qualities we celebrate and often treat as innate, such as intelligence, strength, and courage, are developed through practice rather than fixed at birth. It is inspiring and motivating to see others grow. On a trivial note, today’s date is a palindrome 2020-02-02 (ISO 8601 format).

Things I wrote this week

I attended the Banff Moutain Film Festival when it toured in Oxford, and my thoughts are in this post.

I finished an overdue race report on the 2019 Blenheim Palace Half Marathon.

Things to share this week

Transparency and Teamwork
I’ve been chatting with some friends at work about transparency, and a famous example of extreme transparency in an organisation comes from Ray Dalio’s Bridgewater. A Summary and Table of Life Principles is provided as a free excerpt from his book. On the same topic, I’m still coming back to and digesting Google’s project Aristotle, described in this piece from the New York Times.

19,547 Calories
Kilian Jornet is a professional athlete who enjoys going up mountains. Last year he skied non stop for 24 hours and managed to gain 23 km in elevation, or nearly three “Everest”s. Doing this required nearly 20,000 kcal (as estimated by Strava), so refuelling would take 37 Big Macs (it actually surprised me how low that number is).

Physical Training Update

I am hoping to break 3 hours for the marathon in 2020, but training has been delayed by an Achilles injury. Rest was the right approach, and I’ve tried to substitute indoor rowing and indoor cycling as low impact alternatives for endurance training. It has been satisfying to see the numbers for weekly “Relative Effort” (based on heart rate) on Strava go up, but as I resume running this hasn’t translated well into speed over ground.

It is frustrating to have to hold back and turn down opportunities to train with friends. It is teaching me the importance of focusing on long term goals to make smarter choices in individual sessions. I’ve also been thinking about this TED talk about the importance of training “easy”. I tend to train “hard” every workout, but this may be less effective the fitter I become. When new to running, race-pace and training-pace can be the same thing, but as fitness increases maximum effort sessions take more recovery time and are more likely to result in injury. Some hard sessions are necessary, but not every session can nor should feel hard.

I’ve also learned that for indoor rowers, power into the machine (watts) is proportional to speed cubed, rather than squared as I would have guessed. That is, an additional 50 W of power brings a 500 m split time of 2:31.8 s/500 m (or 100 W) down to 2:12.6 (19.2 seconds faster), but the next 50 W increment only saves 12.1 seconds more, then 8.6 s, then 6.5 s, until halving the split to 1:15.9 (i.e. doubling the speed) requires 8 times more power at 800 W.
