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.
How it works
Pick objective + horizon
Choose a template and set your timeframe – 6 to 16 weeks.
Get a structured plan
Phased blocks with runs, strength, and planned recovery. Each session has a clear purpose – tempo for threshold, eccentric work for descents, easy runs for recovery.
Adjust week by week
Log sessions, review suggested adjustments, and progress through your block.

Frequently asked questions
No. Most templates are development-focused – building climbing power, speed, or endurance without a specific race date. If you do have a race, the Race Peak & Taper template structures your entire build-up around it.
Both. During plan setup you set your current weekly volume and experience level. Session intensity, progression rate, and recovery are adapted to your profile. Beginners start with 3-4 sessions per week and gentler volume ramps.
Yes. Connect Strava or Garmin from your account settings. Activities sync automatically and are matched to your planned sessions. With Garmin, you can also push upcoming workouts directly to your watch. All sync data is stored in the EU and cached activity imports are automatically deleted after 7 days.
Mark sessions as skipped and the system will suggest adjustments for the following week. It can reduce volume, swap session types, or extend your plan timeline – all within safe progression boundaries.
