Trimetra

Trimetra is the training app that gets you real results — for running, cycling, walking, swimming, inline skating and triathlon. No static schedule: a weekly plan that adapts every day to what you train and how you recover, calculated from your own data instead of averages.

THE RIGHT STIMULUS EVERY WEEK
Trimetra builds your week from build, quality and recovery days. Missed a workout, got sick or life got busy? The plan shifts automatically. Your load stays balanced through fatigue, fitness and freshness, so you keep progressing without over- or undertraining.

LEARNS FROM WHAT YOU ACTUALLY DO
After every session, Trimetra compares plan and execution. Thresholds, zones and intensity move with your form — whether you train by power, heart rate or feel.

RECOVERY STEERS THE PLAN
Sleep, resting heart rate, HRV and weight come together in one recovery picture. When your recovery drops, the app favours endurance or rest over quality.

TRAIN TOWARDS A GOAL
From your first 10K to a marathon, gran fondo or full triathlon: build, peak and taper blocks are placed automatically towards your goal date — including a pacing plan and fueling advice for race day itself.

WALKING AND INLINE SKATING COUNT IN FULL
Walking and inline skating are planned sports, not an afterthought. A walk is steered by time on your feet rather than by pace — that is the quantity that fits. With a multi-day trek on your calendar, the plan stacks walking days back to back instead of scheduling isolated long days: one day per step, and never further than you have already shown yourself. Inline skating is steered by heart rate, because there is no power meter and pace is not comparable across asphalt, wind and wheels. So for those two you get no finish-time prediction — you do get a build-up.
