Your plan doesn't know you skipped yesterday.
Your plan doesn't know you're still fatigued.
Your plan doesn't know you at all.
SUFR does.
How it works
Connect your data
Strava, Garmin, Apple Watch and more. SUFR starts where you are.
Set your goals
Races, distances, dates. Tell SUFR what you're chasing.
Train adaptively
Get a plan that evolves with you. Every session, every day.
Built on science
Personalized engine
An advanced system learns your individual response — how you adapt, recover, and perform. Your plan gets smarter with every session.
Intelligent periodization
Base, build, peak, taper — structured automatically around your race calendar. Multi-race seasons with priority weighting.
Multi-sport platform
Run, ride, swim, gym — balanced in one plan. Concurrent training principles keep every discipline progressing.
Life-aware adaptation
Missed a session? Sick? Traveling? The plan adjusts. No guilt, no wasted weeks — just intelligent recalibration.
Every endurance sport
Running
5K to ultra. Road, trail, track.
Cycling
Road, gravel, time trial.
Swimming
Pool and open water.
Triathlon
Sprint to Ironman.

Run-bike-run, any distance.
