Endless Endurance is thrilled to bring the Loopy Looper 12 hour challenge to Cooper River Park. This event is a great first-time ultra or marathon, a chance to run any distance you've been hesitant to sign up for, or a chance to really push yourself to your limits. Dont think you could run for 12 hours straight? No problem! If you are someone that wants to run one loop at the start, take a break for a bit and then go back out, thats absolutely fine and we encourage it!

Not ready to take on 12 hours by yourself? We are offering a relay option! Get some friends and take this on as a 4 runner team!

Loopy Looper - 12 Hour Challenge route

The race will be held on a 3.6ish mile loop on a paved path around Cooper River Park. The course is mostly flat and you will run as many loops of it as you can/want in 12 hours. This is a great location if you have had your eyes set on a distance but have been hesitant to sign up for it due to time cut-offs.

Finisher Rules:
To be counted as a finisher you need to be on location at 6pm and have completed at least one full loop of the course. No medals will be handed out before 6pm! We don’t care if you’re out there grinding out as many miles as possible in the 12 hours or if you ran a loop and spent the rest of the day helping out your fellow runners. You’re still a finisher and you’ll still get your medal. We just ask that if you are not running all day to do something productive like actively helping other runners


Pit Area and Aid Station:
This will be a very well supported event. We plan to have one fully stocked aid station with all the standard ultra running goodies at the Start/Finish line and one water station out on course. The aid station will have things like PB&J, chips, candy, soda, water, sports drinks, pizza, and much more.

At the Start/Finish area at the stadium, there will be a drop/pit area for you to stash your stuff for the day. We ask that you do not bring any tents larger than 10x10!
