The Flatrock 50k | 13.1 | 50/50 Challenge is back!

Remember when running was just… running?! Same. We’re big fans of grassroots ultras, so we’re going back to our roots & bringing you guys one heck of a fun, down-to-earth, no-frills, chill, good old-fashioned trail race!

We’re keeping the prices as low as we can, but the stoke as high as possible! So come on out to Georgia, kick back for a day of Southern hospitality and epic racing on sweet Southeastern single track! (Say that 3x fast.)

Beginner & PR Friendly

Are you itching to try your hand -err- legs at trail or ultrarunning? Or maybe you're on the hunt for a trail PR? THIS IS THE RACE FOR YOU.

If you're looking for epic vistas or mega climbs and descents on mountains, that's not this! Flatrock 50k & half is as good as it can get for your first ultra or trail race and hits the sweet spot of flowing trails with some hills that are just challenging enough to keep it interesting and still throw down some fast times!

This is a true trail race! The route will take runners through undulating trails winding through miles upon miles of trees. The trails are not technical. As for the hills, they’re nothing that will take you longer than a minute or two to climb!

The 50k race will consist of 2 13.1 loops, and 2 5 mile loops. The half will consist of one loop. Both races will take runners to aid stations that are very accessible by their family and friends.

Cutoffs for each distance:
50k - 9 hours
13.1 - 5 hours
50/50 - 9 hours

The 50/50 Challenge

Now for the REAL fun…
Attention all you speedsters out there: If you're feeling lucky or youre hungry for a challenge, you can choose to sign up for the 50/50 challenge.

If you choose this option, when you complete your 50k, you will have the option of either keeping the 50k finish OR continuing for another 20 miles to snag a 50 MILE FINISH.

The challenge?

YOU MUST COMPLETE THE 50 MILES WITHIN THE 50K's 9 HOUR STRICT CUTOFF! And once you commit, you’re locked in!

If you don't? You get ZERO credit for either distance.

If you do? You get a super exclusive 50/50 challenge shirt & a free entry to come back and run again next year!

Think you got what it takes? We'll see!


We are so stoked to bring back the Flatrock Trail Run in October 2024! We learned a lot in 2023 and we are ready to bring you guys a great race experience. If you came to our inaugural race, you can expect the following updates for 2024:

-the long loop will be rerouted to follow an easier visual flow and help reduce any missed turns
-different socks! We will make sure the next batch is totally wearable. :-D
-medals for each distance for finishers upon completion of the race
-race will begin one hour later to eliminate headlamp use

Spectator Friendly

We're all about including family and friends for the fun. So if you've got kids, bring ‘em on out! Harbins Park boasts an awesome playground that'll keep the kids entertained while you channel your inner trail beast. You'll pass by the start/finish line more than once. The aid stations are easily accessible by your crew giving your personal cheer squad ample opps to shower you with love and encouragement.

Swag, Awards, etc
