Week 10: Team Apollo vs Team Poseidon

The community is at 930 members and closing in on a thousand. Most Miles in a Month starts September 1 with two teams, Apollo and Poseidon, and scoring weighted so no sport is penalized: run and hike 1 to 1, bike 3 to 1, swim counts 4x. Thank you to Maple Boost Nutrition for putting up prizes.

What we built last week

• Oura's sleep screen, rebuilt: Oura is being sued over sleep accuracy, so we built the same screen for free on Garmin data
• Replacing Strava Intelligence: rebuilt on data you already own, with insights that actually help
• Garmin Fenix 9 and its Epic feature: what launched, and our own version of it
• The top 5 concepts people get wrong when training with AI
• Rebuilding the WHOOP screens: can you actually cancel your subscription?
• Ben Dhiman at UTMB Mont Blanc: a look at the performance

Coming this week

• The jump height model: your phone camera measuring jump height from flight time, the same method a force plate uses
• The squat form model: every rep graded on depth, knee track, bar path and spine angle
• The aero model: what your position on the bike costs you in watts
• One free platform for four subscriptions: Oura, Strava, WHOOP and Garmin, about $600 a year, consolidated

Community notes

• Growth: 930 members, up from 876.
• NYC Marathon: I am running it in partnership with Endorphins and New Balance, and taking the Athlete OS to a world major. Endorphins' main app is free and their paid AI coaching has a two-week free trial. I only recommend tools I use, and their commitment to free data for every user matches how this community works.
• Strength poll: balancing lifting with endurance training took 10 of 14 votes, so that is what gets built next.
