Running, walking and HIIT

Switch your pace. Let Trotinho watch the clock.

Getting into running with walk breaks? Set your running and walking intervals, choose the repetitions and start. Audio cues help you switch without checking the clock.

It also works for sprint intervals, gym rounds and other timed workouts. Trotinho is an interval timer, not a GPS tracker.
