Racefox Ski: The world’s first real-time digital coach for XC skiers.
Racefox uses a chest sensor to see how your body moves, providing in-the-moment feedback for improved performance in XC skiing. Racefox includes a personalized coach who understands your strengths and weaknesses, and makes sure each training session takes you closer to your goal. The benefits of Racefox are seen after only four training sessions. Racefox integrates with the Health app.

All you need is your phone, headphones and a Polar H10 or Racefox Smartbelt to get started.

RACEFOX HELPS YOU SKI FASTER. 15% FASTER.
The key to becoming faster and increasing endurance is improving technique. Using real-time audio feedback and guided exercises, your Racefox coach can help you improve your form and “find the feeling” that will propel you forward.

UNDERSTAND YOUR LEVEL
The Racefox 8-minute test helps explain your current skiing level, shows where you need to improve, and even predicts your finish time at Vasaloppet.

IMPROVE YOUR SKI POWER
Ski Power measures how much power you put into your skiing. How fast you go depends on the frequency of your poling, how much power you generate in each stroke, the consistency of your technique, and your acceleration as you attack.

ACHIEVE YOUR GOAL
Having a real-time digital coach in your ear as you train, either on the trail or in the gym, helps you develop your technique and respond immediately to changes that improve speed, endurance, and form.

Racefox is a subscription service that includes regular updates and improvements.
