What TrailSplits knows
Beta training plan
Your 20-week training plan
The organizer-confirmed date and distance shape this generic plan. Vertical targets stay blank until course elevation is verified.
23 weeks and 2 days are available: enough for a full progression and taper.
Use it for race-effort sessions and race day. Easy runs stay easy whatever the goal; the plan's efforts come from how you run now.
The plan starts 26 October 2026, 3 weeks from now. Until then, easy running at your usual volume keeps you ready for week 1; the season planner can fill those weeks with base training.
Default starting point: 40 stable km/week, longest recent outing 24 km, 5 running days/week, aiming to finish well.
No connected training history is used. Unanswered details remain conservative assumptions.
No account needed. A kept plan stays on this browser until its storage is cleared; find it under My kept plans, where you can also change single weeks.

Plan assumptions and limits
- Unknown ascent (D+): the engine omits vertical targets rather than inventing them.
- Generic planning guidance from race facts and stated training — not medical care or individual coaching.
- Training distances and durations are approximate alternatives, not pace targets. Use current effort, not a hoped-for finish time. Repeat or shorten a week if recovery is poor; do not make up missed sessions.
