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.
