Are YOU Ready to RUMBLE?


The half marathon your mother warned you about….

Do you love running hills? Do you love running in summer heat? Does the DC area humidity inspire you to get out and sweat it out?

If you said yes to any of these questions, or even if you didn’t, come out and run the infamous Riley’s Rumble Half Marathon or 8K this weekend – SUNDAY, JULY 30th at 7:00 AM!

MCRRC members: Register for free on race day. If you already have a club-issued bib and timing chip, wear them. Otherwise, you can pick them up at the registration tables. (If you have not picked up your chip yet, bring a $5 deposit.)

Non-members:REGISTER ONLINE for both the half marathon and 8K.  The half marathon is $30.00 (plus service fees) and the 8K is $15 (plus service fees). You can register in person on race-day morning, but because there is no runner limit, you could be waiting in a long line. Pre-registering also means we can’t misread your handwritten entry or mistype it into the computer. We want your name spelled correctly in the results!  At the race site, you will be given a bib and timing chip. The chip must be returned immediately after the race, at the finish line.

Everyone: Registration and packet pickup open at 5:30am. Try to arrive no later than 6am to help us get everyone through registration and packet pickup.

Rumble not for you? Be a part of the fun anyways, by volunteering! Click here to volunteer. SSL credit is available for middle and high school students.
