Finish your first ultra. Or your tenth. Train to last.
Periodized trail plans with rule-bounded weekly adjustments. Designed for mountain runners targeting UTMB, Lavaredo, CCC, and more. EU-hosted, private by default.
Built for runners who train with intent
Who it's for
- Mountain and trail runners tackling 30-80 km with real vertical
- Training for climbing, descent, stamina, or speed – not just "more running"
- People wanting a focused training tool – not another social platform
What makes it different
Objective-first plans
Every plan starts with a goal – a race to peak for, or a capability to build. Macro cycles, progressive overload, and planned deload weeks – not random workouts.
Strength integrated
Phase-appropriate strength work is built in, not bolted on. Posterior chain in climb blocks, eccentric work for descents, plyometrics for speed.
Conservative adaptation
Adjustments follow conservative rules – volume limits, progression caps, mandatory recovery windows. Every change is logged with visible history. Adjustments stay within bounded constraints, with a visible explanation of why.

Frequently asked questions
