Harefoot

Turn your Apple Watch into a structured-training watch: the workouts from your intervals.icu calendar or your own plan, step by step with the target on your wrist, race plans that pace you to your goal, and every lap in intervals.icu and Apple Health. Coming soon to the App Store, with your first month free.

A structured workout on the iPhone: each rep against its pace target, 4 of 5 on targetA workout step on Apple Watch: the rep at 4:05 per km, its pace target and the time leftA race on the iPhone: 16.09 km in 1:04:07, 15 seconds under the goal, with its routeA race plan on Apple Watch: 21 seconds behind the plan, and the pace that wins the goal back

Structured workouts

Run the workouts planned in your intervals.icu calendar, or build your own on your iPhone with pace, heart-rate or power targets. The watch shows each step's target, alerts you at every change, and lets you repeat a rep or extend a step.

Training plans

Build a plan for your goal race from a weekly pattern of workouts, or apply one from your intervals.icu library. Move, skip or swap a session and the watch follows.

Race plans

Even, negative-split or custom paces for your race, with the watch telling you how far ahead of or behind the plan you are. Switch goals at checkpoints, and line the distance up with the course's kilometre markers.

Every lap where you train

Each run uploads to intervals.icu with every lap, linked to the planned workout it completes, and is saved to Apple Health with its route and laps. After the run: map, laps, splits and charts, each step against its target.

Right by default

Data pages made for free runs, workouts and races, ready from the first run and adjustable on your iPhone. Auto-pause, spoken feedback, alerts, Water Lock, and your next run in the Smart Stack.

Your season

Distance against your goal, streaks, long runs, time in zones, records, a race prediction, and fitness and form from intervals.icu.
