St. Moritz Running Festival 2026 - running weekend in the Engadin
From 7 to 9 August 2026, the St. Moritz Running Festival fills a weekend with racing at 1,800 metres, and its signature race, the Engadiner Sommerlauf, starts right in Sils.
The event
The festival spreads its races across three days. Friday evening opens with the Cuorsa Mascha Rösa, Saturday belongs to the Run for Fun and the kids' races in St. Moritz, and Sunday brings the main events: the Engadiner Sommerlauf, Run Pontresina and the shorter Run S. An event village with food and music keeps the weekend social between starts. The Free Fall Vertical does not take place in 2026.
The Engadiner Sommerlauf
The classic of the weekend starts in Sils at 10:15 on Sunday 9 August and runs 22.9 kilometres down the valley, past the lakes, through Silvaplana and Champfèr and along the Inn. It is a fast, scenic course with far more descent than climb, which makes it a rewarding first mountain race as well as a quick one for seasoned runners.
Where to watch from Hotel Schweizerhof
Sommerlauf runners staying at the hotel walk to the start line in minutes, with a calm race morning and breakfast timed to the gun. Supporters can cheer the field away in Sils, then take the Engadin Bus down the valley to catch the finish festivities.
