The race starts in Leitza
and crosses the Aralar mountain range
and the beautiful valleys around it. The participants not only have to be quick, but show an incredibly high level of physical fitness. However, you are not obliged to run the 65 kilometres or complete the 7,000 metres of sloping ground
along the route. Just visit the places along the way to cheer on the 700+ runners who take part. You can also take the opportunity to go along the Plazoala railway line greenway
and stop off in a restaurant for a tasty meal of local cuisine.
