| Decision | Official 2026 detail |
|---|---|
| Distance and ascent | 42.5 km; 2,200 m |
| Start | Gjevilvasshytta |
| Waves | 8:00 over six hours; 9:00 under six hours |
| Course cutoffs | Remmasætra 12:00; Vekveselva 14:30; Vangslia 15:30 |
| Aid | Four stations plus finish |
This is not a road marathon with scenery added. The organizer describes technical mountain trail, a high point at 1,389 metres, sustained climbing, and a long descent toward Oppdal. Train time on feet, controlled descending, hiking where appropriate, fueling while climbing, and decision-making in changing mountain conditions.
The published participant information requires a pack with nutrition, drink, wind jacket, head covering, gloves, and a phone; poles and headphones are not allowed. Recheck the current rules and kit before travel. Transport to the start is included and there is no start-area parking.
Mountain weather can change quickly. Stop and seek appropriate care for severe symptoms, and follow organizer or mountain-safety instructions even when that ends the race.

How to use this athlete guide
Treat this page as a decision checklist:
- Confirm the race date and official logistics on the official site close to race day.
- Use the training timeline above to pick a plan length and a start-by date.
- Practice fueling and pacing in long runs (don’t wait until race week).
- Keep race week simple: tested shoes, tested gels, conservative start.
Picking a plan length (simple heuristic)
If you’re deciding between plan lengths, default to the option you can repeat consistently — not the most aggressive one.
- More time (20–24 weeks): best if you’re building consistency, returning from time off, or want a gentler progression.
- Mid-range (16–18 weeks): works well when you already have a steady weekly base and can keep long runs consistent.
- Shorter (14–15 weeks): only if your base is solid and you’re not forcing a big jump in volume.
If a start-by date has already passed, choose a longer plan (or aim to finish strong and healthy rather than forcing peak mileage).
Course + conditions (what should change in training)
Use the course and conditions blocks on this page to adjust your defaults:
- Surface: Terrain.
- Course difficulty: extreme.
- Climate context: Seasonal context: Summer (Northern Hemisphere). Check the race-week forecast and adjust layers and hydration..
Practical implication: the harder the course or the more variable the weather, the more conservative you should be with pacing and the more you should practice fueling under “imperfect” conditions.
Initial pacing and fueling targets
Most marathons are decided late. Until you have training evidence that says otherwise:
- Start slightly conservative for the first 5–10K.
- Fuel early and on a schedule you’ve practiced in long runs.
- Adjust pace targets when conditions are hotter, windier, or hillier than expected.
Tools that make this simpler:
Course pacing signals (what to rehearse)
- Mixed surface: practice transitions (grip, cadence, downhills) so race day feels familiar.
- Hilly profile: pace climbs by effort, practice downhills, and avoid chasing uphill splits.
- Crowds/wind rule: treat headwinds and congestion as “hills” and stay effort-controlled.
Climate-specific adaptations (gear + fueling)
- Plan for variability: pack one extra layer option and decide pace adjustments before race morning.
- Fueling rule: practice carbs early and on schedule; do not “wait until you feel it.”
Race-week timeline skeleton
- 72–48 hours out: travel buffer, expo/bib pickup, keep meals simple, protect sleep.
- 24 hours out: finalize gear, short shakeout if you like it, hydration + carbs, early bedtime.
- Race morning: warm-up timing, bathroom plan, corrals, conservative first 5–10K.
- Post-race: fluids + carbs, keep warm, light walking, and a calm 48-hour recovery plan.
What to verify (close to race week)
- Start time + corrals/waves + any cutoffs
- Course map/profile + any reroutes (and where the climbs/exposed sections are)
- Expo location/hours + bib pickup rules (ID, proxy pickup, deadlines)
- Aid station spacing + what is provided on-course (fluids, carbs, electrolytes)
- Bag drop/finish-area logistics + transport back to hotel
- Weather forecast (race week) and your pacing + gear adjustments
Common mistakes (avoid these)
Most marathon problems are boring, preventable mistakes — usually from adding novelty late.
- Starting too fast because “it feels easy” early.
- Trying new shoes, gels, or hydration the week of the race.
- Under-fueling early, then “bonking” late.
- Cramming missed training into the final two weeks.
- Ignoring weather adjustments (pace targets should change when conditions do).
If you’re unsure, choose the calmer option: conservative start, steady fueling, and protect your sleep.
Travel and logistics
If you’re traveling, optimize for the few things that matter: sleep, simple transport, and a predictable morning.
- If possible, arrive 1–2 days early so sleep isn’t a coin flip.
- Keep race-week walking low (save your legs).
- Plan your morning timeline: transport → bathroom → warm-up → corrals.
- Treat anything marked “unknown” here as a prompt to verify on the official site close to race week.
Training guardrails
- Keep easy runs truly easy so workouts stay high quality.
- Progress one variable at a time (volume first, then intensity).
- Use cutback weeks every 3–4 weeks to absorb training.
- If pain changes your gait, scale back and get assessed.
Verification reminder
Race details change between editions (dates move, routes reroute, and registration rules update). Use this page as a starting point, then confirm time-sensitive details on the official site close to race day.
