Do I need to sign up for Intervals.icu to use IntervalCoach?

Yes. IntervalCoach uses a free Intervals.icu account as the data hub. Training history and workouts stay in the athlete’s own Intervals.icu account, and IntervalCoach reads from it and writes structured sessions back to it. Setting up Intervals.icu is part of the onboarding, and the account itself is free.

Will this work for me if I train across multiple sports rather than one?

Yes. IntervalCoach was built specifically for multi-sport training in one plan. The daily decision considers cycling, running, swimming and strength as a single training picture, rather than treating each as a separate calendar. Hiking and walking are first-class activities too, so triathletes, duathletes, and mixed-sport athletes all sit within the same engine rather than needing a separate plan for each discipline.

How is this different from TrainingPeaks and other static training plan platforms?

The core difference is that IntervalCoach rewrites today’s workout each morning based on recovery and fitness data, rather than handing the athlete a fixed plan to follow. Static plans assume the athlete will execute what was written weeks earlier, even when sleep is poor or stress is high. IntervalCoach reads more than 60 recovery and fitness signals every morning and adjusts the session accordingly. It also connects via Intervals.icu and major device ecosystems, rather than locking the athlete into a single closed platform.
