Early Start & Course Closures

 

As much as we’d love to spend days/nights/weekends at our favorite race sites, our permits only allow us to be on site for a limited amount of time. We are required to close the course to stay within those limits and, unfortunately, participants will not be permitted to continue once the course is closed.

 

If you are concerned about being able to finish the marathon in the allotted time, we want to help you achieve your running goals, so we offer an early start for those who need a little more time. Early start marathoners will receive a chip time, but are not eligible for age group awards or series awards. The course may not be marked, course marshals & police may not be on course, aid stations may not be set, and the course is open to the public. The early start is ONLY for marathoners. 

 

Those that are not participating in the marathon and start early will not receive an official time and will be disqualified. Additionally, participants who continue after being asked to stop will be disqualified.

Timing

This race is chip timed by Silver Circle with a chip start. Your time will start when you cross the start line and stops when you cross the finish line.
