Plan smarter.
Train smarter.
Race better.
Tri-Train connects your activities, analyses your performance with AI and helps you progress more consistently — for beginners to Ironman athletes.
How it works
Three steps from raw data to structured training progress.
Connect
Link Strava and Garmin in a few clicks. Your activities sync automatically every 15 minutes.
Analyse
AI automatically analyses every activity. TSS, Power Curve, VO2max estimation — all calculated, nothing manual.
Improve
Use the training planner, the calculators and the Claude connector to get faster — in swimming, cycling and running.
What it looks like
Screenshots from the demo account — no stock imagery, no mockups.
Your training status at a glance
Fitness (CTL), fatigue (ATL) and form (TSB) from your own training load, next to today’s session and your planned volume.
Build a training plan and keep it in the calendar
Swim, bike and run in day, week or month view, with weekly TSS and kilometres beside it. Sessions come from the plan generator or the interval builder.
Performance analysis instead of gut feeling
The PMC curve over months, ramp rate, heart rate zones and power curve — calculated from every activity, not entered by hand.
