Challenger 24km

The most demanding path of all three categories; it is marked and it passes through hiking and trail paths. From 3.5 to 5.5 km of the route there is no path, but the area is passable.
Challenger category passes 80 m through the sea (up to the hip height) and it doesn’t cross Via Ferrata. There are no refreshments; water is available from the Malin spring on the 15th kilometre, but the participants must bring sufficient amount of water.
