* The minimum age to participate in the CBSR must be 18 years old at the start of the race.

* In order to participate to the CBSR we will require a medical certificate informing that the participant is able to run stage-race ultra-distances. The certificate must have been made in the previous year before the start of the CBSR (from the 24th of April 2019 to the 17th of September 2020) and must be uploaded to your private zone before the 17th of September 2020. The organization recommends the certificate to be accompanied by a stress test (ECG during effort) in order to assess correctly the runner’s condition.

The exclusion of liability must be signed and uploaded to your private zone before the 17th of September 2020.
