Since 1986, this top mountain run along the longest glacier in the Alps – the Aletsch glacier – has been organised in Bettmeralp. Since then this mountain run – also called the glacier run – has continuously progressed. In the past, the distance up to the 2,650 metre high Bettmerhorn amounted to 17.5 km. In 2000, after careful preparation, the distance and route were adapted to the runners’ standards. Since then the glacier run has been known as the ”Aletsch Half-Marathon“.
As the name indicates, runners have to master a 21.1 km distance with an altitude difference of around 1,050 metres. The marathon starts at 1,950 meters above sea level.
