What is the Personal Accident Insurance?

This Personal Accident Insurance is offered by the organiser's insurer so that you are correctly covered during your participation in the Tro Bro Leon Challenge.

It is optional but is strongly recommended.

As you may know, the vast majority of your usual insurance policies (particularly your insurance provided through your bank cards, 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 Tro Bro Leon Challenge with Giant.

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.

It guarantees the following accidents that may occur during the event:

• in the event of death or total or partial permanent disability (due to this accident), the payment of a capital (within the limits of the purchased insurance option),

• coverage of medical costs (within the limits of the purchased insurance option), and, if necessary, repatriation.

This 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. YYou may purchase the cover from the insurer of your choice, from your federation or from Marsh, organizer’s broker, whose proposed insurance (detailed notice and application form) can be consulted and downloaded by clicking on the link below.

You can subscribe to the option of your choice during your registration for the event or at any time before the start of the event

Are there feeding stations on the route?

Feeding stations will be set up at established points along the route.

Are there rules I need to follow on the roads?
