Join us for the Fat Sass Switchback Challenge! Runners can sign-up for a 5K (3 loops) 3 hours or 6 hours. The 1 mile loop with 291 ft elevation gain starts and finishes at the Locust Grove Picnic Area off of Glen Ave in Millburn, NJ at the South Mountain Reservation.

Fat Sass Switchback Challenge routes

The 1 mile loop has 291 ft elevation gain: 1/2 mile up the steep Lenape Trail and 1/2 mile down the switchbacks. Yup, that's right! It's the reverse of the 2018 event! Don’t expect any PRs at this race. 96.15% of the course is technical, rocky trails. 3.85% (0.04 miles) is pavement. The course will be marked. Start/finish at the Locus Grove Picnic Area. Take the Lenape Trail all the way up until you hit the Crest Drive Pavement. Turn LEFT and run along the pavement until you get to the American Flag. Run down the rocks and turn right to stay on Lenape (yellow). Make a left to head down the switchbacks all the way to the Locust Grove Picnic Area. There are portapottys at the trailhead parking lot.

Event Details

What’s Included
This is a self-supported fat-ass event! No finishers' swag, no aid stations and no whining (unless you don't see Sasquatch, then you can whine a little). We will provide water at the start/finish (but this is a cupless event, so be sure to bring a water bottle, cup or hydration pack). BYO-fuel! Sharing is caring--don't be sassy with your stash--bring extra to share with the rest of the Sassquad.

Can I bring my dog?

Sorry, but Padfoot has to stay at home for this race.

Can I sign my kids up for the Fat Sass?

Yes! This is a family friendly event. Be sure to register your child separately and agree to the waiver for minors. And make sure to keep track of little Jake and Elwood before during and after the race. We only have 1 search-party and they're already out there looking for Sasquatch.

What's the weather like in Millburn, NJ in July?

Blazing hot. Humid. Though based on this past winter, we may have snow flurries. Be ready for anything.
