4 months ago I signed up for a half Ironman to force myself to get fit again. At that time I couldn’t even run a 5k without my back hurting. It’s been super fun to work on my fitness as a project. Some recap/learnings:
- I ended up training for 2.8h/week on average and was happy with my time & no injuries. I didn’t have any endurance sports background. Definitely don’t need 10h/week like what people day.
- AI coach: Used a LLM wiki instead of off-the-shelf stuff. Fed it some books, put it on @NousResearch, and gave it my life (garmin, 8 sleep, calendar, bloodwork, dexa scan etc).
- It got really good at adapting plans based on my biometrics & progress, and giving specific feedback like fixing cadence & vertical oscillation.
- Best investments: Chest HR monitor and bike fit.
- Basically every problem is caused by tight hip flexors.
- Eating and drinking properly during the race is way more important than I expected.
- Total cost ~$3.5k: bike $1600, signing up $600, bike fit $450, and ~$1k in shoes, clothes, gear, extra food.
- Hardest parts on race day: Last 5k of the run; having to eat almost 2k calories while exercising; driving home afterwards.
