Elite runners

Compulsory accreditation for rider assistance

Team managers accompanying elite athletes and those wishing to assist a runner must apply for accreditation in order to be authorized to follow their runner on the course and have access to the feed zones.

As a reminder, runner assistance is only authorized 100m before and 100m after the feed zones. Any assistance provided outside the authorized zones will result in a time penalty being applied to the riders receiving the assistance.

Accreditations will be distributed at the Chamonix Nordic House
(51 Avenue de la Plage, 74400 Chamonix-Mont-Blanc).
