The first starting areas (elite, preferential and red) are only accessible upon presentation of proof of your performances. This is why you cannot sign up for them directly.

To save time, we invite the runners concerned to sign up in the yellow starting area and to send us their proof of performance immediately by email to to change your starting area.

Your trainers already know all about it and your legs soon will too: you have signed up for a sports event. You therefore need to provide a medical certificate (or a copy of one) on your time to account.

REMEMBER, the certificate must fulfil several criteria:

  • It must mention “no counter indication to taking part in athletics competitions” or “no counter indication to taking part in running competitions”.
  • It must be dated within one year of the Run In Mont Saint-Michel by Harmonie Mutuelle 2019

To avoid mistakes, we suggest you use the model certificate available online:

You are exempt from providing a medical certificate if you fall into one of the following two categories:

  • You hold a licence from the Fédération Française d'Athlétisme
  • You hold an FSCF, FSGT or UFOLEP licence (which must mention the word “athletics”)

In this case, come with a copy of your licence to collect your race number (please note: the licence must be valid on the day of the race).

This Personal Accident Insurance is offered by the organiser's insurer so that you are correctly covered during your participation in the Run In Mont Saint-Michel by Harmonie Mutuelle 2019

It is optional but is strongly recommended.

As you may know, the vast majority of your usual insurance policies (particularly your car insurance, insurance provided automatically through your bank cards, household insurance, bank loan insurance, etc.) totally exclude any participation in sports events either on an amateur or professional basis, and therefore exclude the risks involved in your taking part in the Run In Mont Saint-Michel by Harmonie Mutuelle.

It is therefore important that you check the extent of the cover provided by your normal insurance policies (and the exclusions) and, if you are not sufficiently covered or not covered at all, you should consider taking out the proposed insurance policies by clicking on the link below.

This insurance will cover you if you have an accident whilst taking part in the event, whether or not you were responsible and whether or not there is an identified responsible third party. You are only covered during the event from the time you cross the starting line until the time you cross the finishing line or you abandon the event.

In the event of an accident during your participation in the event, it covers:
• medical costs (within the limits that you have chosen),
• in the event of death or total or partial permanent disability (due to this accident): the payment of compensation (within the limits that you have chosen)

This cover Individual Accident is optional but highly recommended. It can be taken out in addition to any existing insurance you may already have or if you are not already covered. You may purchase the cover from the insurer of your choice, from your federation or from Aon, organizer’s broker, whose proposal (detailed notice and application form) can be consulted and downloaded by clicking on the link below. You can subscribe to the option providing the minimum cover for this offer during your registration for the event and other options by downloading the relevant form here and sending it directly to Aon (
