For athletes at every level
Train with clearer feedback, not guesswork
Protern connects video and performance data so athletes can clearly see where time is gained or lost. It is used by World Cup athletes, national teams, and developing racers who want more objective insight into their training.
Whether you are refining details at the highest level or building fundamentals, Protern helps turn runs into clear, actionable feedback you can understand and discuss with your coach.
Why athletes choose Protern
Top athletes do not rely on feel alone. They use clear feedback to understand what is actually happening on snow.
See performance clearly
Review video with speed and timing shown directly on the run.
Compare runs objectively

Review on your own
Look deeper into your runs between sessions or after training.
Share the same view

Designed to support coaching, not replace it
Protern is built to complement the coach’s eye. It helps athletes understand what their coach is seeing by linking objective data to the same video used for feedback.
This shared reference makes conversations clearer and more productive. Athletes gain deeper understanding, and coaches spend less time explaining and more time coaching.

How Protern fits into team training
Protern is used by teams of all sizes, from small training groups to national programs with athletes training around the world.
