CRUX „Count Rudolph Ultra eXtreme“ – the first winter ultra run in Switzerland
You can expect trail running through the hills and mountains of Tösstal of 28 KM or 56 KM. It crosses the Kantons of Zurich, Thurgau and St. Gallen to the upper Lake of Zurich.

This event was born 2011 with the support of Untamed Adventure. The runners and founders of the first hour had all a background in Adventure Racing. Grant as a co-founder left Switzerland and with that the run almost found its end after the premier. We found the event to be unequaled in both beauty and spirit and after a quick talk to Grant we decided to take over the idea and keep the CRUX running.

The start and transport of your equipment will be organized. Everything between lays in your hand. Fun, challenge and adventure are the main terms. Ranking list and timing are only a side service and therefore not official. All important information as far as maps, contacts and logistics as well as the (not too seriously meant) background you’ll find in the following pages.

See you
