Information to all racers

We have collected the most important information about the races below so that you as a participant can get answers to your questions without having to wait. A Race PM is sent the week before the race containing the latest information. 

About the ice and safety

  • To ensure the quality and safety of the ice (Edsviken and/or Norrviken) we collaborate with Danderyds Municipality (Edsviken) and Sollentuna Municipality (Norrviken). They are responsible for measurements and the plowed paths on each lake.

  • The thickness of the ice must be at least 12cm for the municipalities to plow and several test drillings take place continuously before, during and after plowing. Could be good to know that  about 3-4cm is enough to carry a person. 

  • If the ice is approved, the Half Marathon and Marathon go over Edsviken on up to 7 occasions and a course of approximately 10km on Norrviken. In total, there will be approximately 6km of ice running during the Half Marathon and 16km during the Marathon. But the course is usually revised up until the day before so follow us on social media and read the Race PM sent out before.

  • We only run on the ice if the crossings are secured, no exceptions!

  • If the ice is judged to be too weak or in too bad a condition, the course is revised and running takes place on a winter trail around Edsviken and/or Norrviken.

  • When running around the lakes, it will be on a combination of asphalt, dirt road, forrest path and slightly more technical trail.  

About the marking of the tracks

  • The courses will be marked with orange Enduro arrows to show the way, extra signs at tricky intersections and Challengize flags at the end of all ice crossings. We will have staff at some, but not all, ice crossings. 

  • Regardless of the course, the race will be run on more or less prepared roads, dirt roads, paths, snow-covered rocks, roots and on ice. Expect it to be slippery regardless of which of the courses apply.

  • You should therefore wear suitable winter shoes. If not with spikes, preferably trail shoes or running shoes with "broddar". If it's dry and snow-free, normal running shoes or trail shoes will be finee.

About Arena Edsvik and transport

  • Start and finish for all races takes place at beautiful Edsvik, address Landsnoravägen 42, Sollentuna.

  • Canicross means that you and your dog run together during the entire race. The dog must be on a leash at all times and you can start your race 15 minutes before the mass start to reduce stress for the dog. 

Mandatory equipment

  • Apart from the race bib, which must be clearly visible from the front, there is no mandatory equipment.
