What TrailSplits knows
Beta training plan
Your 11-week training plan
The organizer-confirmed date and distance shape this generic plan. Vertical targets stay blank until course elevation is verified.
10 weeks and 2 days are available instead of the normal 16. The plan stays conservative rather than cramming the missing weeks.
Keep the goal finish-focused and do not increase volume faster because the race is close.
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.
Default starting point: 35 stable km/week, longest recent outing 18 km, 4 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
- Road race: the plan is distance-driven and no vertical target is prescribed.
- Only 10 weeks and 2 days are available instead of the normal 16 weeks; this is a compressed, finish-focused build.
- 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.
Week 1: Build consistent easy running19.9 km; long run 16 km
- Long run
100 min (about 15.9 km). Build relaxed time on feet at conversational effort. Practise eating and drinking on longer easy runs; easy pace is not a reason to skip fueling. For runs lasting 1 to 2.5 hours, 30 to 60 g of carbohydrate per hour is a useful starting range; beyond 2.5 hours, build toward 60 to 90 g per hour if you have practised it and tolerate it. Adjust fluid to your needs and the conditions.
- Recovery run or hike
25 min (about 4 km). Keep this genuinely easy, or substitute an easy hike.
