If you plan on participating at a 13:44 minute pace per mile or slower, please be aware that our permit dictates that the streets that comprise the marathon route are reopened to vehicular traffic at 1:30pm. On-course support (aid stations) will close at this time.

We also suggest that walkers and slower participants consider carrying a hydration pack that accommodates water and snacks.

Will you have Pace Groups?

How do you capture my finish time?

Your official race bib has a timing strip on the back, so do not remove this strip. Once you cross the start line your timing strip activates, and will not stop until you cross the finish line. In addition, we will have various timing mats on the course to capture your progress along the way. Athletes vying for prize money will be judged on gun time, while age group awards will be issued based upon tag (chip) time.

Do you allow participants to walk in the races?

Of course! We do ask that you adhere to the time limit rules.

We do not have any restrictions on the use of headphones, phones, or iPods. We strongly discourage the use for safety reasons. If you make a decision to wear a music-playing device during the race, please keep it at a low level so you can hear special instructions from course officials or emergency vehicles.
