The National Capital 20 Miler is Washington, DC’s premier fall marathon tune-up race. Taking place on the C&O Towpath, the 20 Miler offers runners a flat, fast out-and-back course with water and nutrition support at regular intervals.

Runners can also elect to participate in the Janet Braunstein 5 Miler, which begins twenty minutes after the start of the 20 Miler.


Work off those extra holiday calories at one of our most popular club races, the Turkey Burnoff 5 and 10 Mile race at Seneca Creek State Park in Gaithersburg. The course is scenic (double loop for 10 miles) and you’ll burn off that third helping of pumpkin pie on the gently rolling hills. The park deer occasionally make a cameo appearance and they don’t brake for runners! All runners need to be in the park by 7:50 AM.

The course has rolling hills while running across a dam and through the woods on paved roads. In addition to the 5- and 10-mile races, there is a free kids’ race.


Dashing through the snow to an 8K race today… Put on some festive holiday gear and join us at the Rockville Senior Center for the Jingle Bell Jog. The course winds through a quiet residential neighborhood and is followed by our annual meeting, open to all members.

Free for MCRRC members; $15 plus fees for non-members over age 18; $10 plus fees for non-members under age 18. The kids’ run is free but participants must register in advance.


Three distances – 8K, 2M, and 1K – all starting and finishing at Kensington Town Hall.

The 8K runs through historic Kensington, going past Warner Mansion, along Antique Row, beside 120+ year-old houses and around Noyes Library, the oldest library in MoCo. Then it heads down Kensington Parkway to an out-and-back along beautiful Beach Drive before returning to the Town for a fast finish.
