It is possible to change athletes at almost all our events (with some exceptions).
It is imperative that the person giving up his or her number writes us an email with the following information about the replacement: surname, first name, full postal address, date of birth, email address and mobile phone number.
The substitute athlete must also have an MSO account. If this is not the case, please ensure that the account is created before contacting us so that we can make the change immediately.
Once the change is effective, the new athlete can go to his MSO account under "my events" to update their registration services (T-shirt size, emergency number, etc.)
