Can I unsubscribe due to an injury or an impediment?

No cancellation gives the right to a refund 60 days before the event. If it is an injury and you have a medical certificate, you can contact us at

Can i run with my dog?

Yes, if the dog is kept on a leash and if you start at the back of the pelonton so the other runners will not be disturbed.

I tried to subscribe but the system failed and refuses to let me subscribe a second time?

The easiest way to avoid this problem is to re-subscribe and change one character of your name.

I can't find my name or starting bib in the list of pre-registrated runners (published a few days before the race)?

The "group" entries are not included in the published lists of the individual pre-registrations because it is the group captains who will distribute the group numbers.

Is it possible to collect the starting bib of someone else ?

Yes, but you need to know his exact name and his starting bib number. No piece of identification is needed.

Yes, from 08h30.
