Dizzy Fifties

We’re back for the 22nd annual Dizzy Fifties, and this year we’re going big — with new distance options! The original 50K remains the heart and soul of this grassroots trail classic, but for the first time ever, we’re offering 20-mile and 10-mile options. That means more runners, more trail love, and more dirt-slingin’ fun.

Whether you’re an ultra veteran or just dipping your toes into the trail world, Dizzy welcomes you. Same great looped course, same laid-back vibe, same low-key celebration of the trail community — just with more ways to join in.

All distances follow the same figure-8-style loop. We’ll refer to this as the “big” loop. It starts with a flatter, faster section utilizing the South Plateau Loop, Firetower and the Family Bike Trail (a.k.a. Bucca), so keep an eye out for bikers and share the trail. Around 6.4 miles, you’ll pass near the pavilion aid station (but you don’t have to stop unless you want to access aid). The second half of the loop dips down off the plateau, loops through Logan-Keith and the infamous climb up Sinks, and then brings you back to the pavilion. You must check in at the arch after you complete each 10-mile “big” loop.
