From 2003 - 2014 the Graubünden Marathon took place annually. This was considered one of the hardest mountain marathons in Europe and of course it also had a half marathon route.
The start is at 1'240 m above sea level near the monastery in Churwalden.From there it goes through the village and then towards Büel, Foppa. From Foppa we go downhill via Mittelberg to Parpan. Over the Parpanerhöhe to Valbella and finally once around the Heidsee to the finish in the village of Lenzerheide.
