Where do we stay?

We welcome walkers, runners and hikeres. You don't need to be super fit, just a reasonable level of fitness. 

For the 100km you need to be a minimum of 18. 

The 8km (Day 3) is open to all age groups. 

What's the after party?

To finish, you have the chance to sample part of this unforgettable way of life and enjoy our medal ceramony and after party, joined by the Mayor of Fundu Moldovei, with customary BBQ accompanied by mamaliga, homemade cheese and bread.

please note:

Equipment: Failure to carry ALL the compulsory equipment will lead to a 2-hour penalty or disqualification. It is a mountain race and the weather can change very quickly. It's for your own safety.


Littering will lead to a 2-hour penalty or disqualification.


Gates: Leave gates as you find them open or closed. We are working hard to build a relationship with the local shepherds. If you leave a gate open the shepherd might lose livestock. If this happens the responsible runner will have to bear the cost of replacing the livestock.
