What TrailSplits knows

Beta training plan

Your 8-week training plan

The course day is not recorded; this preview uses the event's first day. Confirm your course's day before keeping a plan or booking travel.

Compressed build

8 weeks and 2 days are available instead of the normal 12. 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.

Goal time?

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 12 October 2026, 1 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: 28 stable km/week, longest recent outing 13 km, 4 running days/week, aiming to finish well.

No connected training history is used. Unanswered details remain conservative assumptions.

Stable recent km/weekTypical completed volume across 4–6 weeks. Longest recent outing

Your longest comfortable run lately, not a lifetime best. Recent consistencyStable load matters more than one unusually big week. GoalA performance goal needs a stronger demonstrated base. Running days availableCount days you can genuinely sustain. Experience at this distanceExperience changes how a short runway is interpreted. Current training statusThis answer is not saved. A generic plan cannot diagnose or clear a return to running.

Still being enriched: organizer date confirmation and course elevation or GPX. Future previews may use new evidence; kept copies remain unchanged.

Plan assumptions and limits

Unknown ascent (D+): the engine omits vertical targets rather than inventing them.
Only 8 weeks and 2 days are available instead of the normal 12 weeks; this is a compressed, finish-focused build.
Generic planning guidance from race facts and stated training — not medical care or individual coaching.
Consecutive long trail outings are not established in your recent training. This plan keeps one main long outing with short easy sessions immediately around it; removed minutes are not made up. Race ambition and planned weeks do not establish this experience.
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.

Run the 31.4 km as planned: start controlled and use the fuelling and kit rehearsed in training. In the 36 to 48 hours before, eat mostly carbohydrate (about 10 to 12 g per kg of body weight a day, from familiar foods), and have a familiar breakfast two to four hours before the start.
Sun 6 DecPost-race recovery
Prioritize rest, food, fluids and gentle movement; do not schedule a workout by default.
