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.
