Like our past editions, in order to keep our event authentic and friendly we have decided to cap the number of registrations to less than 100, including pairs and relay.  It will provide everyone, us included, with a very pleasant, stress free and family-like race. But that doesn’t mean it will be a piece of cake !

As we’re both nostalgic of the first 4 editions, in terms of participants and atmosphere, we’ve decided to give an extra chance to those who took part in our previous editions… but everyone will have a chance to take part and register during this period. At the end of the process, we’ll draw !

What do you get ? GPS tracking device, cap, finisher beer(s), finisher party (best Sunday brunch ever tasted after an ultra race) and a special JUBILEE gift, our smiles and wicked humour!

SOLO 150.- CHF

PAIR 260.- CHF


OPEN ON THE 1st DAY OF SPRING and for the next 10 days till the 1st of April

Our REGISTRATIONS will take place from the 21st of March to the 1st of April 2024.

This year, we will proceed as follow:

  • first come, first serve
  • once our quota is full, you will automatically put on the lottery list
  • alumni on the lottery list will have so many more chances to participate as the number of editions they took part in (you did all the editions, your name will be added 5 times to the list)
  • as in the previous editions, we will cap the number of participants to less than 100 trackers
  • if it isn’t full, we will of course extend the deadline


Our registration process is now closed.

Our lucky future participants have now been personally notified by email and have until 1 May to confirm their registration.
We will then fill the vacancies with those on the waiting list.
