From the Organizer

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.
5K: $40 per participant through May 31; $45 through July 31, $50 until the race sells out or the race starts.
10K: $50 per participant through May 31; $55 through July 31; $60 until the race sells out or the race starts.

All participants must register online and in advance of coming to the packet pick-up. 

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.  

Race proceeds will benefit Special Olympics Virginia, the Committee for Dulles Community Outreach, and the Washington Airports Task Force, all 501c3 nonprofit organizations closely affiliated with Dulles Airport.

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.

Awards: Top male and top female for both races will each receive a certificate from United Airlines, Dulles Airport's hub carrier, good for a round-trip anywhere that United flies in the continental United States; Alaska; Caribbean; Canada; Mexico and Central America, plus a weekend overnight stay for two at the Washington Dulles Airport Marriott!

Awards will also be given to the top male and female finishers for each race in the following age groups: 12 & under, 13-17, 18-30, 31-40, 41-50, 51-60, 61-70, 71 & over. All awards must be claimed within 2 weeks of the conclusion of the race.

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!

About This Sport

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

The 10K is the distance where running stops feeling like a starting point and starts feeling like a sport. Long enough to require a real training block. Short enough that race day is fully manageable for a first-timer who's put in the work.

Race day energy at a 10K is community at its best — strangers cheering you by name, people moving toward the same goal, an atmosphere that solo training can't replicate. It's fast enough that you'll spend the whole race pushing rather than managing your effort.

This is also the distance that builds the base for everything else. Most athletes who go on to run half marathons, do triathlons, or compete in HYROX started here. What you need: running shoes fitted to your stride, a training plan, and the race on your calendar. The registration is what makes the deadline real.

How long to train: 4–8 weeks for most fitness levels.
