The registration process is modified. This year, you will first have to pay for your race, then in a second time, complete the registration form and download your medical certificate or a copy of your current sports license. You will be registered to the Ultra Marin once the registration service has validated your document. (This operation may take a few days). Read the Ultra Marin 2020 regulations
