Custom workouts for iPhone and Apple Watch
Build Custom Running Workouts
Start with simple run/walk intervals or build a session with warm-ups, timed work, recovery, rests, repeats, and a cool-down. Save your workout on iPhone, then sync it to Apple Watch.
Start with the intervals you know.
For a straightforward run/walk workout, set the run and walk durations, repeats, and optional warm-up and cool-down. Name it and reuse it on another day.


Shape every step.
Create a longer sequence with different work durations, recovery intervals, rests, repeat blocks, and custom cues. Preview the complete session before you run it.
Advanced workout authoring and multiple saved workouts require Interval Run Pro. The app is free to download.
Build on iPhone. Run from your wrist.
Sync a saved workout to Apple Watch and run it without your iPhone nearby. Watch voice cues, haptics, and controls guide the session.

Choose a starting point.
Use a bundled workout as a starting point, or create your own sequence from scratch.
