What TrailSplits knows

Beta training plan

Your 5-week training plan

The organizer-confirmed date and distance shape this generic plan. Vertical targets stay blank until course elevation is verified.

Maintenance and race-specific rehearsal

4 weeks and 1 day cannot replace a full build. This plan preserves existing fitness, rehearses race demands and tapers.

Proceed only if the stated recent training genuinely reflects your current preparation.

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.

Default starting point: 25 stable km/week, longest recent outing 8 km, 4 running days/week, aiming to finish well.

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

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: course elevation or GPX. Future previews may use new evidence; kept copies remain unchanged.

Plan assumptions and limits

Road race: the plan is distance-driven and no vertical target is prescribed.
Short-runway maintenance mode does not raise weekly load above the stated stable starting point.
Only 4 weeks and 1 day are available instead of the normal 8 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.
