SGRAIL78 2026 - gravel triathlon festival in Silvaplana
.webp)
From 4 to 6 September 2026, SGRAIL78 returns to Silvaplana: a gravel triathlon festival that swaps wetsuit-to-tarmac convention for lake swimming, gravel riding and trail running in the Upper Engadin. Hotel Schweizerhof in Sils Maria is an official partner.
The event
The main race combines a 1.5 km swim in Lake Silvaplana, 64 km of high-alpine gravel and a 12.2 km trail run around Surlej. A Lite distance, team formats and a kids' duathlon on Saturday 5 September open the weekend to every level. The founders' line sums up the spirit: not about time, but about the experience. Expect a community-driven festival village rather than a results-obsessed race expo.
Your base as official partner hotel
Hotel Schweizerhof welcomes athletes and supporters with what a race weekend actually needs: direct access to trails and gravel for the final tune-up, massages for afterwards, balanced regional cooking and quiet nights ten minutes from the event area. Participants find an exclusive discount code for the hotel on the SGRAIL website.
