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

Happy Monday AAC Team! We are 876 strong today, up from 835 last Monday. 41 new faces and the participation in here lately has been awesome to watch. First, lets talk event. 16 of you are signed up, so we are running two teams of 8 with people covering swim, bike, run and hiking on both sides! And we got our first sponsor - Maple Boost Nutrition is putting up prizes for the winning team! On top of that every winner gets a $25 gift card to The Feed. That one is not sponsored (yet), that is just a gift from me :). Most Miles in a Month officially kicks off 9/1 and teams get released this week. You can still join before the start, just fill out the form and I will get you on a squad: Most Miles Form Sign-up Here is how we are weighting it so that every discipline actually counts: - Run - 1 mile = 1 mile - Hike - 1 mile = 1 mile - Bike - 3 miles = 1 mile - Swim - 1 mile = 4 miles That is built off time, not distance. An hour of running, an hour on the bike and an hour in the pool all come out to roughly the same number, which is the entire point. Thank you @Ian Antonoff for helping coordinate and brainstorm with all of this! Secondly, a recap of what we pushed last week: - Connecting Claude to Zwift - and actually pushing real workouts to it, not just talking about them [link] - Endorphins app updates - what changed, plus 10 prompts to run against your own training data [link] - Diagnosing a bad run with Claude - the run that felt terrible, and what your data says actually happened - Backyard ultra training plan - off Last Soul Ultra weekend, built from your own history [link] - The beginner's guide to ultramarathons - off Leadville weekend. Everything from "what even counts as an ultra" to the prompt that builds your first plan [link] - Strength training as you age and what it does to muscle health - plus a strength coach prompt that interviews you, reads the research and books your next 90 days [link] - Buzz demo results - it is genuinely very cool. @Joshua Thomas , @Luis Dominguez , @Ed McKelvey , @Andres Jaramillo , @Giuseppe Carbonari , @Jake Williams , @.Kostya Panov and @Robby Gentry all have been helping demo. We are now opening it up to the rest of the team this week. This will continue to be a working group that will experiment with competitions, events, and fitness tracking. So come join when you get done Advanced Lessons tag #buzzready and I will send you the link! - Athlete OS Library prompt numbering is done - @Lars Johan Ulveseth thank you for the patience on that one, it took me about three weeks longer than it should have!

The number one indicator of performance in runners isn't VO2max, it's vVO2max - the slowest speed at which you hit your VO2max. It combines the engine and the efficiency into one number. A study in PubMed put 17 trained runners through a 16k time trial and vVO2max explained the finishers 94% of the time, while VO2max only got 81%. The test is simple enough to do this weekend. Flat track, fresh legs, set a timer for 5 minutes and run it all out at an even effort. Whatever your average pace is for those 5 minutes, that's your number. And 5 isn't a round number somebody picked - a guy named Berthon worked backwards from world record data in 1997 and calculated it, then an independent group ran the math again in 2024 and landed on 4.97 minutes. I ran my own 3200 test last week 18 seconds negative split... which by this test's own rule means I paced it instead of maxing it, so my number reads slow. Get to run it again 🙃 FYI: your first one will probably read slow too. It's a pacing skill before it's a fitness measurement. The prompt digs through your last 6 months, finds any run that could reasonably be a test, and if there isn't one it hands you the test and builds the plan off your result. Full guide and prompt here: vVo2 Max Prompt Here Fun one to run this weekend if anyone's got a track nearby! Kevin

Finished the day I have been most looking forward to😄 - the dashboard.. Basic enough at the moment. but will get more onto it and looking as good as me soon 😄

Hey all! I finally got my website where I want it, atleast for now lol!! Ask me again tomorrow, right? I drew heavy influence from @Luis Dominguez. His page is a monster! This thing tracks all my fitness routines and all corralling data, training zones, supplements, scale data, etc., everything works offline with the telegram app Thanks @Kevin Rudd, you're the man!
