The Clemson Experimental Marathon is a A FREE Trail Marathon, Half-Marathon, and 10K in the beautiful Clemson University Forest, hosted by the Clemson Experimental Trail Runners Club.
It's never too early to start training for next year! Our next race will be in the Spring of 2027.
Stay Tuned: Details Coming Soon!
This year's Half Marathon and Full Marathon will follow the same route, with the half Marathon running one lap and the Full Marathon will run two laps.
The first half of the loop will take you down to Lake Issaquena, following the lake shore before crossing a road and heading up Wounded Knee Trail and into the northern most section of the forest.
When you make it back to the start area, you've completed just under half of the course (6.5 miles) and can use the aid station and bathrooms there.
There will be no more bathrooms along the course.
The second half of the loop will follow more difficult trails in the "Waterfalls" and the "Keowee Heights" areas.
Awesome Views of Lake Hartwell
You will have to do a small amount of road running. We will have cones out but please be considerate of cars. There is another aid station at miles 8.3 and 21.4 at the end of the road.
The finish is a long, almost a mile uphill. You can do it!!!
Half Marathon Elevation Gain: 1,184 feet
Marathon Elevation Gain: 2,368 feet
The 10k course is a classic Experimental Forest Loop that descends down to Lake Issaqueena and follows the lake before climbing back up to the highpoint at the finish line!
First, a gradual, mostly downhill section that leads to the lake.
Second, a beautiful, flat two miles with gorgeous views of the lake.
Then finally, a slow, gradual, snaking uphill that suddenly turns very steep about ~.66 miles from the finish line
Be sure to save some in the tank for this last uphill!
Total Elevation Gain: 427 feet
T-shirts are the driving force of how we host the race for free. Every shirt purchased helps us put on this event for future years. Thanks to everyone who buys a t-shirt!
