The insurance is independent from the Race organisation. 

Please follow the process described here:

Registration is exclusively online, as for all races, subject to availability. 

A common mistake is that parents forget to create a personal MSO account for their child. 

You have to send your request by email to specifying the race you are registered for, the one you would like to enter and your estimated time of completion for this new race. 

As stated in the Rules and Regulations, going for a shorter distance does not trigger any financial compensation. 

On the ohter hand, going for a longer distance implies the payment of the difference between the fee paid and the current fee for the new race. 

In order to be able to take the part to the « EXTREME » race, you must have some mountain experience.

To evaluate this experience, the organisation's mountain guides will base their evaluation on your answers to the questions below. Their decision is final.

If you have any doubts when answering the questions, we recommend that you turn to one of the other Matterhorn Ultraks races. 

In case of rejection, you will be guaranteed a starting slot in one of the other races of the event or a refund.


I certify that I can be autonomous in the high mountains, off-trail in bad weather and/or fog conditions.
Moreover, I took good note of the time barriers.
