36: Berlin Marathon Debrief

There is no better confirmation that training works than Sam's (aka globerunnergriff) journey.He went from 125kg to a 2:22 marathon in 3 years, driven by grit and consistency. We go into his training from the early injury-riddled days of starting out, then pushing through and building up the mileage over time.NB: Sam's been a kaizen user for over a year primarily tracking progress trends, although he'd NEVER fine tuned his predictions. So whilst his progression is an accurate, the final numbers are off (which is mentioned). We dialled everything in after the recording.Sam's training is all available here: https://www.strava.com/athletes/32613852--kaizen⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://kaizen.app.link/milesbetter⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://www.strava.com/clubs/runkaizen⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://runkaizen.com/⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://www.instagram.com/runkaizen/⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://www.strava.com/athletes/32067191⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Josh: https://www.strava.com/athletes/1721750

If you want to see a pro's training and prediction data in kaizen, then check this one out.Jimmy Whelan joins us to analyse his training from his 61:37 HM debut in Valencia 2025, and also dive into the training data since then for some of his other performances on the roads in 2026.We compare the data between some of his more impressive training blocks over the past 12 months, and some of the key themes that keep popping up when he's in his best shape.Jimmy's training is all available here: https://www.strava.com/pros/3356275--kaizen⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://kaizen.app.link/milesbetter⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://www.strava.com/clubs/runkaizen⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://runkaizen.com/⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://www.instagram.com/runkaizen/⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠: https://www.strava.com/athletes/32067191⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Josh: https://www.strava.com/athletes/1721750
