Analysing terrain data
The world's cross-country skiing elite is at the start here every year on the occasion of Davos Nordic.
The trail is also popular with amateur athletes.
The route leads from the Bünda area along the forest to the Obersand and over the Flüelabach to the other side of the valley.
The route then climbs past the Adventure Park Färich, a rope and bike park in summer.
Key point of the cross-country trail: the famous "Cologna-Stutz", named after the chosen Davoser and most successful Swiss cross-country skier of all time.
On the 236 metre long ascent of the route, some athletes bite their teeth out.
At the small settlement Waldji the highest and at the same time the turning point of the track is reached.
Parallel to the ascent, we descend a few hundred metres before crossing Flüelabach.
Along the stream you can "bolt" for about 1.5 kilometres before reaching the Obersand again.
The last kilometer is also mostly slightly sloping and leads back to the starting point of the round.
