For a comprehensive list, visit the Washington Running Report.

For some interesting August and September races, check out the events below:

The ROC (Ridiculous Obstacle Course) Race is being held this Saturday. Morning registrations are sold out, but as of Aug. 6, afternoon reservations were still available.

On Fridays in August, the Pacers Events hosts its Lost Dog 5k Series. Bring your dog if you’ve got one, or you have the option to “Rent-A-Mutt,” and give some exercise and companionship to a shelter rescue for the run.

D.C.’s Rave Run was originally scheduled to take place on Aug. 17. It has been postponed, according to its website. However, whenever it happens, this race, filled with “music and light stations, neon-clad runners and a thriving after-party” is still sure to be a blast.

For a more relaxed, tranquil run, head out to Clarksburg, MD, for one of EX2’s Blue Crab Bolt 10Ks. The races are “Fun and challenging and include a mixture of winding single-track hiking trails, stream crossings, grassy fields, and minimal pavement,” according to the race’s website.

The Ellicot City Memorial Run is also on the 17th, in, surprise, Ellicott City. All proceeds benefit two scholarship funds and the Howard County Fire and Rescue Services. Registration closes Aug. 15.

Meanwhile, in Leesburg, on Sunday, Aug. 18, you can run in the Leesburg 5k, or if you’re feeling extra plucky, the 20k.

And the Run n’ Mate 5k social running series hosts another race Aug. 23-24 in Alexandria. www.runnmate5k.com

The Annapolis Ten Mile Run takes place Aug. 25. It’s been listed as one of the nation’s top 10-mile races by Runner’s World. A great way to find some room for a heap pile of crab legs for lunch.

On Sept. 1, head to Greenbelt for the Larry Noel 15k Race and 3k Fun Run. Some hills for the strong, some straight-aways for the swift make these courses both fun and a challenge, according to the race’s website.

And on Sept. 8, there’s the Parks Half Marathon, from Rockville, MD, to Bethesda.

Clubs: As with the races, there are dozens of local area clubs to join. Your best bet is probably an Internet search to see which club is closest to you, but a few include:

The DC Running Club, the DC Roadrunners Club, the Prince George’s Running Club or the Montgomery County Road Runners Club (one of the region’s largest clubs). All offer opportunities for running, racing, and sweat-and-sneaker fueled esprit-de-corps.
