Five ways to train better and ski faster with Protern.io

Since launching Protern, we’ve watched some of the world’s best alpine ski teams use GPS-based performance data and video to improve athlete performance.

Coaches consistently tell us the same thing: Protern changes how you coach and how athletes understand their skiing.

With a lightweight sensor and software built specifically for alpine ski training, Protern supports clearer feedback, stronger comparisons, and better long-term performance tracking.

Below are five practical ways teams use Protern to train better and ski faster.

1. Compare each athlete to themselves

One of the most powerful ways to improve performance is to compare an athlete to their own previous runs.

Using clear performance comparison, coaches can quickly see how changes in line, tactics, or timing affect results from run to run.

Instead of relying only on comparisons between teammates, athletes can see exactly where they improved and where time was lost relative to their own best execution.

When using Protern live during training, this feedback appears shortly after the run. Athletes can review speed, sections, and outcomes on the lift and apply adjustments immediately.

This tight feedback loop supports faster learning and more deliberate repetition.

2. Ski at race speed during training

Training intensity does not always match race intensity. That can create a gap between preparation and performance.

With Protern, coaches can monitor speed patterns across the entire run and confirm whether an athlete is truly skiing at race pace.

By connecting performance data directly to video using data-linked video analysis, athletes can see not just how fast they skied, but where they built speed and where they backed off.

This builds confidence and reinforces race-ready execution under training conditions.

3. Focus on sections where skiers can improve

Improvement often comes from specific parts of the course, not just overall time.

Using the tools explained in How Protern Works, coaches can define sections and analyze performance within targeted terrain, transitions, or rhythm changes.

This allows teams to isolate challenging combinations such as jumps into tight turns or terrain break-overs that disrupt speed.

With objective section data and video review, athletes can understand how tactical adjustments influence both the targeted section and the sections that follow.

4. Understand how line choice affects speed and time

Different routes through a section can have significant downstream effects.

By combining GPS path data with video and performance overlays, teams can evaluate how line choice influences speed carry and finish time.

Comparing multiple runs, either from the same athlete or across teammates using side-by-side comparison, helps clarify where differences accumulate.

Instead of debating impressions, coaches and athletes can base decisions on measurable differences in execution.

5. Monitor and analyze performance across the entire season

Long-term improvement requires consistent tracking.

Protern supports season-wide analysis, allowing teams to review trends in speed, consistency, and execution over months of training.

This aligns with fast and easy workflows, where data collection and review fit naturally into daily training without adding administrative burden.

When performance trends are visible across sessions, coaches can identify whether an athlete is progressing, plateauing, or regressing and adjust training focus accordingly.

Train with clarity

These five strategies reflect how alpine ski teams use Protern to make training more objective, more efficient, and more actionable.
