## The short answer

TrainerRoad plans cycling, triathlon and off-road riding, moving you through base, build and specialty phases to race day while its AI picks each workout and adjusts in real time from your history, performance and recovery; it detects FTP without a test and sends workouts to Garmin, Wahoo, Hammerhead or Zwift. phase.fitness plans riding next to strength and bodyweight skills in one periodized program, writes the rides to Intervals.icu and Garmin as a share of your threshold, and rewrites the next phase from the rides and the lifts together.

## What TrainerRoad is

A cycling training app whose AI picks and adjusts each workout, for indoor trainers and outdoor riding, with plans for cycling, triathlon and off-road.
