Hey squad! With the September Most Miles Challenge wrapping up next week, wanted to propose to the group to see who would want to run it back for October? It's been super fun to track and follow people as they train! Some folks are putting up serious effort! One of the challenges that we faced with this challenge, as some of you know, is that there really isn't a good way to create a challenge with different disciplines (we've been doing a lot of dumb manual calculations). Where you can actually weight each discipline to make the playing field even across Swimming, Biking, Running and Hiking. @Simon Burbidge actually went ahead and created an ios and android app to solve this exact problem! So we were thinking of running back the same challenge and trying out his new build. @Jake Silvia I know that you mentioned you were working on something similar too. Maybe you and Simon can connect and share ideas! Fill out the poll below if you are interested in an October version of most miles, but this time automated 😎. Kevin

Glad you're here. I'm Kevin, an ultrarunner & triathlete (Leadville 100 was my most fun race). I'm not a tech guru. I got curious about AI, realized I could build training tools tailored exactly to me from my own data, and it actually worked. Now I want to teach you to do the same and connect with people building cool things in fitness with AI. That's the whole idea: learn something genuinely interesting, build stuff that's truly yours, and do it alongside like-minded people. Zero coding required. Five steps to start: 1. Introduce yourself in the feed. Something like: "Hi, I'm Steve, I run trail ultras and can't wait to build with AI!" 2. Complete the intro poll so we know we can build the content around what you want: Athlete AI Poll 3. Watch Start Here course (top of the Classroom). Two minutes. 4. Do Day 0 in the 7-Day Challenge: Set Up Your Workshop. 5. Post in Wins as you finish each day, tagged (#Day0Ready). We celebrate every one. The setup day is the hardest part, and we get everyone through it. Stuck? Post what you tried and someone (often me) will get you unstuck. Let's build. Follow the road to The Rut.

We are 835 strong today, up from 789 last Monday. 46 new faces in seven days and a ton of you came in from the triathlon side, so welcome! First, the event. The votes are in and Most Miles in a Month took it, 10 to 8 over the daily challenge drops (daily challenge will be our second event!). So that is what we are building. @Ian Antonoff and I are working on sponsorships and getting sick prizes for the winning team. Running, cycling, swimming and hiking all count. Will release the weighted numbers when we kick it off. Only thing left to do is confirm for those people who are in! This one we will use a google poll so that we can get email addresses and phone numbers: SIGN UP HERE Secondly, a recap of what we pushed last week. I was traveling for a few days so this one is a little tighter than usual: 1. The #1 thing people get wrong connecting Garmin to Claude - you hand it your data with no baseline, so it invents workouts that have nothing to do with the athlete you actually are 2. vVO2 max - the single best performance indicator for endurance athletes, how to find yours, and how to actually move it 3. VO2 max vs running economy - two numbers everyone treats as one, and the one that is really deciding your race time 4. 7 running heart rate zones and how to calculate yours with Claude 5. COROS August update - what actually changed and whether any of it matters 6. Google Pixel Watch 5 dropped - the rundown and how it compare to Garmin's suite 7. 4 ways to use AI to run better - the simple ones, for anyone just getting started 8. Buzz demo group - group is live and we are working through kinks of the platform but at first glance it seems really power! Hopefully can share results by end of this week. Thanks again @.Kostya Panov for surfacing it 9. Classroom housekeeping - the Athlete OS Library prompts are still on my list, apologies @Lars Johan Ulveseth this week got away from me, but I will get it done this week!
