The Pyrenees Stage Run is a 7 day stage race that begins in Ribes de Freser, Spain. The race crosses 5 National Parks and finishes in Salardú Spain with two stages in Andorra. The PSR offers the possibility to cross the Pyrenees following the classic GR11 route.

Brent and Tom ran the Transalpine Run in 2017 and had so much fun they decided to do another multi day European stage race. They convinced Jesse it would be a great idea if he joined.
