Information about the different legs

No service stations during the bike leg

Parking capacity on the bike leg is very limited. The roads are narrow and cannot accommodate many support cars parked side by side at the same time.

Service stations during the marathon leg

No permanent support stations are available during the first 25km of the marathon, but there are some water stations, toilets and mobile support from Red Cross. There are food stations up Zombie hill.

Mountain safety checkpoint at Stavsro

After 37.5 kilometers of the run, you leave the tarmac road and enter a stretch of rocky mountain path for the final 4.7 kilometers of the race. There is risk of extreme weather on the mountain. We therefore have a special checkpoint to ensure that:

  • You are fit to continue on to the finish.
  • Both you and your support team have the necessary equipment in your backpacks, including warm clothes, food and drink. You are required to carry your own equipment.
  • No athlete will be permitted to enter the mountain alone! If your support team is unable to accompany you to the top of the mountain, you will be held back and connected with the next athlete to arrive.
