Fall is a spectacular time to race through the nation's capital. The summer heat fades, the humidity drops, and the city's iconic monuments and tree-lined streets make for a memorable 13.1-mile tour. Whether you're a first-timer looking for a flat, fast course or a seasoned runner chasing a new PR, DC's September half marathons offer something for everyone. Here are four upcoming races worth adding to your calendar.
DC Half Races — Saturday, September 19, 2026
This long-standing favorite (quality score 62 out of 100) takes runners past the Washington Monument, Lincoln Memorial, and along the National Mall. The course is mostly flat and closed to traffic, making it a great choice for a fast finish. The post-race party in Freedom Plaza adds to the festive atmosphere. Registration typically opens early and fills quickly, so plan ahead.
2026 20th Abebe Bikila Marathon & Half — Saturday, September 5, 2026
Named after the legendary Ethiopian marathoner, this race celebrates its 20th anniversary in 2026. The half marathon course winds through scenic Rock Creek Park and past historic landmarks. With a quality score of 49, it's a smaller, community-focused event that offers a unique experience away from the big-city crowds. The date also makes it a perfect Labor Day weekend adventure.
Autumn Georgetown 5K & Half — Sunday, September 20, 2026
Starting and finishing in the charming Georgetown neighborhood, this race (quality score 48) is known for its picturesque route along the C&O Canal and the Potomac River. The autumn colors add a special touch, and the half marathon is challenging but rewarding with some gentle hills. It's a great option if you want a quieter race with a neighborhood feel.
2026 20th Abebe Bikila Marathon & Half (Second Edition) — Saturday, September 5, 2026
Wait, that's the same race as above? Actually, this is a separate listing (quality score 44) for the same event date. It might represent a different registration option or charity entry. Either way, the race itself is the same: a scenic, historic run through Washington, DC, on Labor Day weekend. Check the details to see which entry type suits you best.
