My first 100km run

April 2020 cycling challenge

Towards the end of March, my uncle sent our triathlon group a challenge he was thinking of doing; dubbed the "1000 challenge". There weren't any specifics and I assumed he was talking about 1000km of cycling. I called him later that day to ask him about it and he clarified

How to solve low 4iiii Precision power meter readings

I recently managed to get a 4iiii Precision left-only crank power meter. I fitted it and did a 40 minute indoor session. I have a dumb trainer, but I've found the power curve online. It was showing that I could expect ~200W for 30km/h on a certain setting. Instead,

Zone 2 training

I spent most of 2017 and 2018 running with little structure or knowledge of pacing. When I first started, I kept trying to PB my 5km time literally every single run. A lot of my time was spent injured from ramping up too quickly, and running too quickly. I bought

Automated GitHub releases for Rust projects using Actions

I've been using GitHub Actions more and more across the projects I maintain. It's a great offering and integrates well into GitHub. There are a few Rust projects I have where I wanted to automate the publishing of prebuilt binaries to the GitHub releases page. I've seen others do it

A good standard for endurance sports

I was recently talking to my uncle about the sort of achievements that would be good to achieve as a semi-competitive age-grouper. That is, you're not new to the sport, but also not in an elite category. In the end, we decided a time 1.5x slower than the elite

Avoiding double builds in GitHub Actions
