Come out and join us for this year's race in the beautiful Chamna Natural Preserve! Halloween costumes are strongly encouraged - in fact there may be a prize or two handed out for best costumes! Race T-shirts are available for purchase along with your registration. Order a shirt by September 15th to ensure time for printing. The race distances are 6k, 10k, and a half marathon. There will also be awards and snacks for all entrants after the race. Special prizes from our sponsors will also be given out. After the race you can hang around, cheer for the other runners and congratulate the finishers! This will be a fun family event. Dogs are also welcome, but must be on a leash. A big "Thank you" from Stephanie, Charlie and Jason!
The half marathon is a double out & back with a loop in the middle. The 10K course will follow the first out & back and the loop of the half marathon course. The 6K course is a big loop. The courses are on as much dirt trail as possible (with an occasional rock thrown in). The half marathon and 10K will include some sections of pavement. The course will be marked with fluorescent tape. Course maps will be emailed to all entrants as race day draws near!
