About this app

TrailMath builds structured trail running and ultramarathon training plans, from 30 km mountain races to 100 km, 100 mile and multi-day ultras of 200 km and beyond.

Pick your goal race. TrailMath generates a periodized plan around your distance, your vertical gain, and the days you can actually train, then adapts it as the season goes on.

The plan changes shape with the race, not just its length. Under 80 km it builds a classic block. At 100 km and 100 miles the Sunday long run gives way to back-to-back weekends. At 200 km and beyond it trains restarting on legs that have not recovered instead of one heroic long run, and gives you eight weeks to recover afterwards.

STRUCTURED TRAINING PLANS
- Periodized trail running plans: Base, Build, Peak and Taper phases
- Terrain-aware sessions with real elevation targets
- Integrated strength training (eccentric, plyometric, stability)
- Weekly volume progression with automatic deload weeks
- Full-year seasons: pick a start month and the plan fills 12 months

COACH
- Explains why each week looks the way it does
- Adapts your plan when work, travel or illness gets in the way
- Swap, replace or reschedule sessions, always with your approval
- Rescues a broken week: what to keep, what to move, what to drop

STRAVA SYNC
