Mavinty is an AI endurance coach built by an amateur 3× IRONMAN finisher with AWA Silver 2020 who got a 2021 Kona slot he never raced. 3 races. 18 months. Public record: Gandia Half · Oct 2026 → Valencia 70.3 · Apr 2027 → Italy Full · Sep 2027. Reads your morning HRV. Pushes structured workouts to your watch. Adapts when life happens.
I built this for myself first. Then I realized other amateurs need it too.
After Bolton 2021 I got a Kona slot through rolldown. The email is still in my inbox — Aug 2, 2021. I never made the start line. L4-L5 disc protrusion. Five years of trying to come back, gaining 10kg, watching fitness disappear.
Real coaches charge £200-400/month and check in twice a week. Training apps gave me charts but not decisions. Plan generators didn't know about my back.
So I built Mavinty for myself. An AI that reads my morning HRV, knows about the injury, knows I can't ramp like I used to, and tells me exactly what to do today.
I'm an amateur. I have a job. I train at 5am. I bonk sometimes. I miss workouts when family stuff happens. Mavinty was built understanding all that — because I'm the user.

This isn't an app for someone learning what TSS means. Most of these fit you:
Finished at least one endurance event
Wear a sports watch (Garmin / Wahoo / Coros / Polar / Suunto)
Comfortable with TSS, FTP, training zones
Have a race on the calendar (or planning one)
Want morning data analysis, not weekly summaries
