Race Across Switzerland is part of the Race Across Series — a family of self-supported road ultra events modelled loosely on the RAAM format and run across multiple countries. The Swiss edition is staged in the Grisons (Graubunden) region and offers multiple distance categories ranging from 200 kilometres up to approximately 1,000 kilometres, with the longer distances taking riders through the full spectrum of Swiss alpine terrain. The series attracts both amateur ultra-endurance riders and seasoned long-distance competitors. Grisons is the largest and most sparsely populated canton in Switzerland, a landscape of high mountain passes, remote valleys, and picturesque villages where Romansh, German, and Italian are all spoken. The route passes through or near some of the most celebrated alpine passes in European road cycling, including significant climbs above 2,000 metres. The event runs in late July, typically in hot and dry conditions at lower elevations but with the possibility of thunderstorms and cold temperatures at altitude. Multiple distance options make the event accessible to riders building toward longer events as well as those targeting the maximum distance. The Race Across Series events share a consistent self-supported ethos: no support vehicles, no crew, no outside assistance. The series runs events in Switzerland, Spain, France, Quebec, and Benelux, giving riders who complete multiple editions a sense of progression through different national landscapes.
