Platform features

Everything a coach needs
in one place.

Built specifically for sailing coaching - not adapted from generic fitness software.

Training Load Model

Banister TRIMP - CTL (fitness), ATL (fatigue) and TSB (form) calculated daily from every Strava session.

GPS Activity Maps

Every Strava session mapped. Routes, speed, heart-rate overlays - all visualised on interactive charts.

Season Planning

Phase the year from base blocks to championship peaks. Coaches set the plan, athletes follow it live.

Coach–Athlete Chat

Direct messaging with video support. Send post-session feedback, technique clips, and tactical notes instantly.

Live Sessions

Drop GPS marks on a live map during training. Athletes join from their phone. Review mark positions after.

Sail Analysis

Max speed progression, personal bests, speed vs HR efficiency. Identify which conditions produce peak performance.

The science

Evidence-based training load.
Not guesswork.

Eventyr uses the Banister TRIMP model - the same physiology framework used in elite Olympic athlete preparation. Every session is quantified so you always know exactly where your athletes stand.

CTL (fitness) builds over 42 days - reflects aerobic base and training adaptation.
ATL (fatigue) tracks the last 7 days - shows accumulated stress from recent sessions.
TSB (form) = CTL − ATL - tells you whether an athlete is ready to race or needs recovery.

CTL - Chronic Training Load

A 42-day exponential moving average of daily TRIMP scores. Represents aerobic base and long-term fitness.

ATL - Acute Training Load

A 7-day exponential moving average. Tracks recent fatigue - the short-term toll of hard training.

TSB - Training Stress Balance

TSB = CTL − ATL. Positive means fresh and ready to race. Negative means accumulated fatigue.

TRIMP Score

Duration × ΔHR × 0.64 × e^(1.92 × HRr). Captures session intensity weighted by heart rate reserve.

Who it's for
