Group pre-registration is possible for the 90km, 42km or 23km Mont-Blanc.

• Group registrations must be for the same race (minimum 2 people and maximum 10 people per group).
• Group registrations are only possible in the case of a random draw.
• If a group consists of more than 10 people, it will not be entered in the draw.

The only advantage of group registration is that all group members have the same draw result, whether positive or negative. The probability of being drawn is the same for all riders, whether pre-registered individually or as a group. Each group member must fill in the "group code" information on the registration form. The code must be created by the 1st member of the group to register and then passed on to the other members of the group. It is then up to the group leader to know who makes up his or her group.

Be very careful when entering the group code, as in the event of a code error, group members will not be grouped together under the same group. We recommend that you do not use spaces or special characters in the group name, only capital letters and numbers. Example of a group code: MBM189 (this is an example, please do not use this code).
