The GPX files for the courses will be available the week before the event. We do this to protect the privacy of the landowners who so generously open their fields and properties to us so we can all enjoy these trails.
That’s why we kindly ask, and sincerely thank you, not to enter private property to train before the race. Thanks to everyone’s respect, we’ll be able to keep running in these incredible places for many years to come.
Please remember that anyone who does not respect this guideline may be identified and sanctioned by the organization, with penalties that may include disqualification.
The GPX file will be sent through the WhatsApp broadcast groups and by email to all runners.
This distance will have two start waves, designed to ensure a smooth, safe race start that suits each runner’s pace. This creates the best possible conditions to enjoy the course, the competition and the mountains without bottlenecks.
Waves will be assigned based on the UTMB Index, an international performance indicator based on results obtained in races recognized by the UTMB system.
Elite athletes and runners with the highest UTMB Index will be in Wave 1, while athletes with lower UTMB Index scores and athletes without a UTMB Index will be in Wave 2.
How do I know which wave I’m in? You’ll find your wave number printed in the corner of your bib when you pick up your race kit.
Each runner must start the race in their assigned wave, WITHOUT EXCEPTION.
Any runner who starts the race in an earlier wave than the one assigned will be penalized according to the Penalty System found in the Rules section of the website. Any runner who starts in a later wave than the one assigned will not receive any time deduction.
