How it works

Press start. Put the phone away. Sprint.

Outpacer times every sprint and rest for you, calls out what’s next, and measures each effort with GPS and your heart rate. Afterwards you see exactly how it went.

Coach

A voice in your ear

As you finish each sprint, the coach says your pace and how it compares with the one before. Then it counts you into the next. You never look at a screen mid-effort.

“Sprint 3. 2:31. 2 seconds faster.”

Insight

Why sprints

Short, all-out efforts. Plenty of rest.

Sprint interval training packs the hard work into a few short sprints with generous recovery. Outpacer’s workouts go from a gentle 6 × 30s starter to the Norwegian 4 × 4, each with guidance on who it’s for and how it should feel.
