Parks Half Marathon
Sunday, September 27, 2026 — Rockville
The Parks Half Marathon is a true gem in the DC area, earning a Runner Favorite score of 85. This point-to-point course takes you along tree-lined trails through Montgomery County’s park system, with plenty of shade and gentle rolling hills. It’s well-organized, well-supported, and a favorite for locals and visitors alike. If you’re chasing a scenic fall run with a fast-feeling course, this one belongs on your calendar.
MCRRC Riley's Rumble Half Marathon
Sunday, July 26, 2026 — Boyds
For those who like a challenge and don’t mind a little heat, Riley’s Rumble is a Standout at 81. Put on by the Montgomery County Road Runners Club, this race travels through the Seneca Creek State Park on technical trails. Expect roots, rocks, and a whole lot of character. It’s a smaller, community-driven event that rewards grit. Just be ready for a summer workout with great post-race camaraderie.
Lock 2 Lock Marathon/Half Marathon/10k
Saturday, September 12, 2026 — Williamsport
If history and flat terrain appeal to you, Lock 2 Lock is a Solid Pick at 64. The half marathon runs along the C&O Canal towpath, passing old lock houses and the Potomac River. The surface is crushed gravel, so it’s gentle on the legs, and the early fall date offers pleasant temperatures. This is a great race for a first-timer or anyone looking for a cruisy run through Maryland’s past.
Run On The Rocks • 10M / Half / 20M
Saturday, September 26, 2026 — Point Of Rocks
Run On The Rocks lives up to its name with a scenic, rocky course along the C&O Canal and through Point of Rocks. This race (scored 57) is all about the adventure — think single-track trails, river views, and a low-key vibe. It’s the weekend before Parks Half, so you could even do both if you’re feeling ambitious. Just don’t expect a PR; expect a journey.
Maryland’s half marathon scene is ready for you. Whether you’re after a fast finish, a trail challenge, or a trip through history, these four races prove that good things come in small packages.
