Methodology
Periodization
Base, Build, Peak, Taper. Systematic volume and intensity progression toward race day.
80/20 intensity
Hard sessions capped at 25%. Same distribution used by elite endurance coaches.
Safe progression
2-4% weekly volume ramp. Running capped at 6%. Recovery weeks at 70% every 4th week.
Guardrails
No hard run after long run or hard bike. Taper managed. The engine enforces what coaches enforce.

How does the periodization work?

Can I export the plan?

Do you store my data?
No. Everything runs in your browser. Your plan is saved in localStorage on your device. Nothing is sent to a server.
Not a coach
We're not replacing your coach. A real coach adjusts week to week and knows when to push or pull back. What we offer is a structured starting point, built on the same periodization and intensity principles coaches use. Export it, make it yours, adjust as you go.
