44: Sam Griffiths' Training, from 125kg to 180km/week 06.08.2026 59minThere 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 -
