Dulles 5K/10K on the Runway
About this race
This is your opportunity for the flattest, fastest course in the area! The runway will be closed off for runners to experience a unique look at the airport grounds, something you do not get to do every day! Run past planes and along the actual landing strip on this certified looped course.
Race Date: Saturday, August 29, 2026. The event will feature both a 5K starting at 7:30 a.m. and a 10K starting at 7:40 a.m. The 10k will run the entire length of the runway.
Free parking for the race at the Smithsonian's National Air and Space Museum, Steven F. Udvar-Hazy Center. The Museum parking lot opens at 5:30 a.m. and will close promptly at 8:00 a.m.
Please allow time to park, pass through security, walk through the museum, and get to the starting line. It is important to start each race on time.
All participants 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 water stations along the course; however, you are encouraged to carry your own water if needed.
Registration Fee: Sign up early! There is a limit of 2,500 runners.

Swag: Participants registered prior to August 1, 2026, will be guaranteed 2025 Dulles 5K/10K tech t-shirts. All others will be given shirts on a first-come, first-served basis. All finishers will receive a one-of-a-kind finisher's medal.

Bag Drop: A bag drop will be available near the starting line. Please use the bag given out during packet pick up for the bag drop. We will be writing race numbers on the bags when they are left at the bag drop.
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.
Photos: Free high-resolution race photos will be available for download. Keep an eye out for our on-course/finish line photographers and be prepared to strike a pose!
Post-Race Refreshments: The Washington Dulles Airport Marriott will provide post-race refreshments. Look for their tent and stop by after the race to refuel!
