About this race
A two-mile grass loop through 120 acres of forest and open field, run under a cutoff that gets one minute shorter every single lap. Forty-five minutes for the first. Fifteen for the thirty-first. Seven laps is a half marathon, fourteen is a marathon, sixteen is a 50K, twenty-five is fifty miles, and thirty-one is 100K. The clock decides when you are done, not you.
Race Day Details
Saturday, June 12, 2027 at Lakewood Nature Preserve, 220 Lakewood Drive, Greenville, SC 29607. Get directions.
Course or Race Highlight
The format is what makes this race. Early laps feel generous — 45 minutes for two miles is a walk in the park, and it very nearly is one. But the window closes a minute at a time, and somewhere in the afternoon the math stops being theoretical and starts being the only thing you can think about. Miss a cutoff and it is over: ring the cowbell, turn in your bib, and go cheer for whoever is still out there.
The course itself is grass trails with rolling hills, open fields, and sections of shade, winding among red cedar and maple through the preserve. You may see white-tailed deer, a box turtle, or a fox. Note that there is NO WATER OR POWER ON SITE, so plan your crew setup accordingly. Bring a tent, a camp chair, and your support crew — Friday evening setup begins at 5:00 PM and overnight camping is available.
The Course
A two-mile loop on grass trails with rolling hills, open fields, and sections of shade, through 120 acres of forest featuring red cedar and maple. Keep an eye out for white-tailed deer, box turtles, and foxes. Important: there is no water or power on site, so bring what you and your crew will need for the day.
Lap Cutoffs
Every lap allows one minute less than the one before it — 45 minutes for the first, 15 for the thirty-first. The pace column is what that cutoff works out to per mile on the two-mile loop. Miss a cutoff and your race is complete: ring the cowbell, turn in your bib, and cheer on whoever is still out there.
Parking
Right on site at the address listed, with opportunities to park along the course, or, if you are running late, in the lot adjacent to the start/finish line less than 100 meters away. There is a $5 fee paid during registration that covers this, so nothing is owed on race day.
Aid Stations
A simple but effective ultra-running aid station at the barn, which is also the start/finish, reached every two-mile lap. Participants are welcome to bring and share their favorite aid station snacks.
Available snacks
Hydration
Wildly Charged is our official hydration sponsor — look for the orange 5-gallon jugs at aid stations.

Race Awards
Last Runner Standing
This is an elimination format, so the win is decided by survival rather than by a finishing kick. If multiple runners are still in it at Lap 31, the first across the line wins. Every finisher who covers at least the 10K minimum earns a medal.
Age Group Awards (Male & Female)
The 1st, 2nd, and 3rd place finishers in each of 15 age categories will earn an age group medal — a custom piece to add to your finisher's lanyard at the end of the event.
Series Recognition
This race counts toward season-long age group recognition in this series:
Giving Back
Every Upstate Race Series event is part of the Upstate Giving Series, which connects our 30 races with 30 nonprofit organizations serving communities across the Upstate. Your registration and any donation you add at checkout go to work close to home — you are not just running a race, you are funding the work of a neighbor. Upstate Giving Series.
Groups & Teams
The Upstate Running Club welcomes all local and regional running clubs to our events — the more the merrier. Calling all running clubs and social run groups: Upstate Race Series welcomes crews of all kinds to join the fun. Whether your squad is full of weekend warriors, sunrise chasers, or runners motivated by the promise of a cold drink at the finish, we've got an event for you.
Sign up, share with friends and local running clubs, and cash in on race discounts and refunds when your team, run club, or band of misfits hits 5 runners or more.
