Ex-CrossFitter, Hyrox and triathlon athlete. I train under a triathlon coach and prepare for Hyrox races — I know the sport from the inside, both as a competitor and as someone who sees daily what coaches struggle with.

I built Athlin because I saw a gap: triathlon coaches can't program functional stations, CrossFit coaches have a bias toward random WODs instead of structured running programming. Hyrox demands both — and no existing tool brings them together.

Athlin is an AI coaching CRM that learns a trainer's style and generates training plans based on Garmin and Apple Watch data. The free tools on this site — calculators, quizzes, checklists — are my way of sharing knowledge with Hyrox coaches before they commit to the full platform.
