Fully self-sufficient: remember to bring your water.
A full aid station awaits you at the finish, whichever course you run. No cups are handed out: your own cup is mandatory on the three long courses.
- Bananas, oranges, dried fruit
- Broth, water, cordial, isotonic drink
- Cereal bars, dark chocolate
- Cheese, dried meat
- Savoury snacks, biscuits, sweets
It's allowed, but only within 100 metres of an official aid station. Anywhere else, personal support and pacing are prohibited.
All courses are marked the day before with tape, ground spray, flags and reflective stakes. If in doubt, the GPX track is your best friend.
Each course has cut-off times at the checkpoints and at the finish. The 2027 times, for the courses in their original direction, will be published with the 2027 rules.
Let a volunteer on the course know, or call race HQ on the number printed on your bib. The organisers will bring you back to Tramelan.
No live tracking for now. Timing points along the course let you follow progress on an MSO terminal at the finish.
Cheering runners on: there's no dedicated spectator zone, so pick your own spot on the trail.
On your chest or stomach, fully visible throughout the race, over all your clothing. Never on your pack or on a leg.
You can leave a bag at the Information stand. It's looked after while you race.
After the race
A shower, a massage, a meal, then the catwalks: the party continues at La Marelle.
Men at the Marelle, women at the CIP gym, just a stone's throw away.
A team of massage therapists is waiting for you once you've showered.
Pasta, sandwiches, pastries, hot and cold drinks, all day long.
The top 3 men and women overall and in each category, on every course. You must be present to receive your prize.
