Please 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 great costumes! 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 awarded based on how cool you are (and perhaps other criteria). Please hang around, cheer for the other runners and congratulate the finishers! This will be a fun family event. Dogs are welcome, but please respect the city dog laws. Dogs must be on a leash or at heel.

The half marathon is a double out and back with a loop in the middle.

The 10K course will follow the first out and back and loop of the half marathon course.


The 6K course is more or less a big loop.

Courses will be dirt trail (occasionally rocky) as much as possible. The half marathon and 10K will include some sections of pavement.

Please note that the course will be subject to change up until race morning. The course will be marked with fluorescent tape.
