About

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. CONNECT YOUR APPS AND WATCH Strava, Wahoo, Withings, WHOOP, Suunto, Polar, Hammerhead or Apple Health — or log workouts manually. Export planned workouts to your Wahoo or Hammerhead bike computer, or as a file.

What's New in Trimetra

1.7

September 25, 2026

New in this version: • The app has new colors, with easier-to-read text and buttons that are easier to tap, in light and dark mode. • How hard a workout felt is now called Effort, with its scale: 7/10. • Stretching adapts to what you do: 1, 2 or 3 times a week, based on what you did in the last two weeks. • A route for a workout now prefers a loop over going out and back on the same road. • If you walk for a few minutes right after a run or ride, the app asks whether that was your cool-down. Link it and it belongs to your workout. • Swimming counts the time you actually swim, without the rests at the wall, and your swim threshold comes from your fastest stretches. • Walking calories follow your pace and the gradient. • Your finds are grouped by category, and you filter your collection by All, Duplicates or Still to find. • After a running race you see your plan next to what you ran, kilometer by kilometer. • Today's workout no longer changes unexpectedly once you have seen it. • When two or more new activities come in at once, you see them together on one sheet. For each one you set the effort and say whether you had any complaints. • "Do you feel ill?" is now a regular question in your daily check-in. • Energy systems shows, for each system, your share over the last three weeks, your optimal range and where your plan takes you by Sunday. • Each kind of text has one fixed size, so the screens read more calmly. • Blood pressure from Apple Health appears in the app. With the measuring week you measure morning and evening for seven days, with reminders and your own average at the end. • Without a subscription you can record and save workouts again.
