Whatever your goal, Racefox can help you get there. Faster.

Before you know it, spring will be here and so will that race you signed up for. The marathon. The 10k you want to crush. The charity race you’re running with work friends. No matter what your race, Racefox can take you to the finish line strong.

Providing custom training plans and live audio feedback, Racefox improves technique and speed within as little as four training sessions. In fact, Racefox runners report a 7% improvement in race times.
