Description: The start/finish location has now been moved to Auburn. The reason for the move is that in the past years, most runners commute through the Hwy 80 corridor, with the race now starting in Auburn, it’ll allow for an easier and faster access to the race. Come and participate in one of the most challenging 50K in the Auburn/Cool area. This event has a total accumulative climbing of over 6000 feet. The name FOURmidable comes from the four major climbs along the course. The 50K and 35.5K distances will cross the famous No Hands Bridge on their way out and climb up K2 (aka-Training hill) towards the top of Knickerbocker Canyon to then descend all the way down to the river. At which moment runners will be right on the other side of the American River canyon from the START area. Runners will then climb up the switchbacks back to the Knickerbocker AS to then cross Knickerbocker creek on their way towards Cool AS and then follow the Western States trail towards Auburn AS. The 35k runners would have completed their run and the 50k runners will then do a 5 mile loop up Cardiac hill before returning to the finish line.
