After an amazing sold out 50K event in 2019, Sierra Eastside Mountain Bike Association (SEMBA) is proud to produce the new Mammoth 50K MTB PedalPalooza. The course is comprised of nearly 90% Singletrack, combined with a significant number of trails designed for passing, and a new and improved finish area with plenty of parking and great for spectators. You won’t want to miss this epic race with a tremendous after party in The Village at Mammoth.

$1 of every race entry will go to supporting the efforts of trails in Mammoth Lakes and the excellent work by Mammoth Lakes Trails. If you would like to donate additional funds and help build our trails in Mammoth Lakes, please click here!
