Ruck a Chuck 50K is based on the course of the old Rucky Chucky 50k; the out and back course runs completely on the Western States Trail starting at the Ruck a Chucky river crossing, where runners that participate in the famous Western States 100 mile endurance run get to cross the river towards Auburn, the final town of their 100 mile journey. During the Ruck a Chuck 50k runners will start running towards Foresthill (opposite of WS100) and once reaching the old mining town of Foresthill they will turn around to head back down towards the river, just like runners do during the WS100 and Canyons 100K. This is a great way to experience another part of the WS100 course and to properly train for Canyons 100k, a WS100 qualifying event.
