Online registration will close on Thursday, September 21 at 8:00 pm. NO ADDITIONAL registrations will be allowed after that time. 

Any registrations after Tuesday, September 19 at 8:00, will only be able to pick up on Friday or Race Day. 

Saturday, September 23, 2023. 
5K will start at 7:30 a.m.
10K will start at 7:40 a.m.

The event will feature both a 5K and a 10K. The 10k will run the entire length of the runway! Both races are flat and fast.

Runners must be able to complete the chosen course and be off the runway by 9:00 a.m. so that it can be reopened for aircraft traffic. To allow for extra time, the final 1/2 mile will be on a connector, so provided you are off the air strip and beyond the final checkpoint by 9:00 a.m., you will have plenty of time to finish! We haven't had a runner unable to finish the course yet!

We plan to have a water station along the course, although you are encouraged to carry your own water, if needed. 

Registration Fee: Sign up early! There is a limit of 2,500 runners

Post Race Refreshments:

Strollers (no registration needed for the child in the stroller) and wheelchairs will also be permitted, as long as they can complete the course by 9 am. 

Spectators:
Because this event will take place on the runway, only registered runners (with/without strollers) will be allowed through the final checkpoint to get onto the course. Spectators will be allowed to cheer their favorite runners along the finish line.
