PeakTrail.Run

PeakTrail.Run is a training platform for trail and ultrarunners — for athletes who want to keep their training data in their own hands.

What PeakTrail.Run does

• Your data: import activities from Garmin or intervals.icu — the data stays yours.
• Training plans with hard rules: progression, taper and recovery are checked, not claimed.
• Trail KPIs: trail-specific metrics, measured against your own baseline.

Two ways to a training plan

• Copy & paste — free: PeakTrail hands you the prompt for plan creation — with your races, dates and constraints. Paste it into your own chat assistant (Mistral, ChatGPT, Claude — whatever you use) and paste the resulting plan JSON back into PeakTrail. No lock-in, no cost.
• Directly in the app: No assistant of your own? Generate plans right in the app. Convenient — but each job calls an external model API. Those exact API costs are what donations cover.

What donations are for

Every core feature is and stays free. Costs only arise with the optional AI plan generation: each job calls an external model API that bills per request. Donations cover exactly those API costs — keeping the AI features voluntary: no paywall, no forced subscription.

Transparency

Every plan job records its token usage, and the job report shows what a generation cost. Support us recurrently or one-off — only if you want to.
