Whatever your level of trailing experience, there is bound to be a course to suit you in the Swiss Alps:

• The easy courses are marked in green and blue. They cover between 5 and 12 kilometres and between 66 and 700 metres of positive altitude difference. Ideal for a first approach, recovery after a competition or an injury. 
• The routes are marked by red and black and have a mileage of between 12 and 25 kilometres and a positive difference in altitude ranging from 900 to 2,000 metres. 
• The difficult courses are shown in orange and yellow. From the vertical kilometer of the Christian Bellet Memorial to the 80 kilometers and nearly 6,000 meters of positive altitude difference of the Swiss Peaks Trail route.
