What TrailSplits knows
Beta training plan
Your 4-week training plan
Available verified course facts inform this plan. Missing elevation never creates vertical targets.
4 weeks 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.
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 5 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: 45 stable km/week, longest recent outing 28 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
- Short-runway maintenance mode does not raise weekly load above the stated stable starting point.
- Only 4 weeks are available instead of the normal 24 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 running45 km; long run 20 km; +700 m
- Rest
Rest or gentle mobility.
- Easy hills + uphill strides
70 min (about 7 km). Start with 10 minutes easy on rolling terrain. Then 6 x 20 seconds uphill strides, strong but relaxed, walking back down between them. Finish with at least 10 minutes easy; the rest of the run is easy on the hills.
- Easy run
60 min (about 6 km). Conversational aerobic running. Keep easy days easy enough to support the key work.
- Easy run
55 min (about 5.5 km). Conversational aerobic running. Keep easy days easy enough to support the key work.
- Long run
200 min (about 20 km). Build relaxed time on feet at conversational effort. Rehearse race fuelling: about 40 to 80 g of carbohydrate an hour from early on, 400 to 800 ml of fluid an hour depending on heat and sweat, and sodium with it (about 300 to 600 mg an hour). Use what you will carry on race day and adjust to your stomach.
- Recovery run or hike
65 min (about 6.5 km). Keep this genuinely easy, or substitute an easy hike.
Week 2: Your longest runs, still at an easy effort45 km; long run 21 km; +2025 m
- Rest
Rest or gentle mobility.
- Easy climbing: run-hike
55 min (about 5.5 km). Climb at a conversational effort, power-hiking the steep parts, and descend with control. Time on hills, not a workout.
- Easy run
40 min (about 4 km). Conversational aerobic running. Keep easy days easy enough to support the key work.
- Easy run
40 min (about 4 km). Conversational aerobic running. Keep easy days easy enough to support the key work.
- Long trail day: part 1
210 min (about 21 km). Use race-like terrain where practical, but keep the overall effort controlled. Rehearse race fuelling: about 40 to 80 g of carbohydrate an hour from early on, 400 to 800 ml of fluid an hour depending on heat and sweat, and sodium with it (about 300 to 600 mg an hour). Use what you will carry on race day and adjust to your stomach.
- Long trail day: part 2
105 min (about 10.5 km). Move easily on tired legs. Hiking is valid; stop if mechanics deteriorate.
Week 3: Reduce fatigue while retaining a small intensity reminder23.1 km; long run 8 km; +700 m
- Rest
Rest or gentle mobility.
- Short uphill reminder
35 min (about 3.6 km). Start with 10 minutes easy. Then 3 x 3 minutes at a strong, sustainable uphill effort, walking back down between them. Finish with at least 10 minutes easy; any remaining time is easy.
- Easy run
40 min (about 4.1 km). Conversational aerobic running. Keep easy days easy enough to support the key work.
- Easy run
40 min (about 4.1 km). Conversational aerobic running. Keep easy days easy enough to support the key work.
- Long run
80 min (about 8.2 km). Keep this comfortable and finish with plenty in reserve. Practise the fuel, hydration and kit you intend to use; treat amounts as rehearsal, not a universal prescription.
- Recovery run or hike
30 min (about 3.1 km). Keep this genuinely easy, or substitute an easy hike.
Week 4: Arrive rested; avoid last-minute fitness work10 km before the race; +0 m
- Easy run
40 min (about 4 km). Keep this short and conversational. The goal is freshness, not fitness.
- Easy pre-race run
40 min (about 4 km). Run conversationally. If already familiar, include a few relaxed strides with full recovery; otherwise stay easy.
- Optional shakeout
20 min (about 2 km). Rest, or jog very easily if that reliably helps you feel better.
- Race day
Run the 138 km as planned: start controlled and use the fuelling and kit rehearsed in training. Fuelling: about 40 to 80 g of carbohydrate an hour from early on, 400 to 800 ml of fluid an hour depending on heat and sweat, and sodium with it (about 300 to 600 mg an hour). Use what you will carry on race day and adjust to your stomach. Afterwards: rest or walk for several days, then short easy runs only, with no hard running for three to four weeks, longer after a long mountain day.
- Post-race recovery
Prioritize rest, food, fluids and gentle movement; do not schedule a workout by default.
- Optional easy movement
Walk or move very easily only if it feels restorative. A return to running is individual.
