Riley’s Rumble
Riley’s Rumble is a summer half marathon held Sunday, July 25, 2027. The course includes hilly terrain and is run in typical summer conditions in the DC area, which are often hot and humid.
Registration for MCRRC members is free as part of the club’s low-key race series; members must obtain a 2026 bib and chip and may exchange older chips or provide a $5 chip deposit if needed. Non-members pay a registration fee of $37.40 for participants 18 and over and $22 for participants under 18; these prices include processing fees. Bib and chip pickup occurs on race morning near the start area and volunteers will assist.
Race permits require participants to maintain a pace no slower than 15 minutes per mile. On-course support includes water, Gatorade, and ice every two to three miles and at the start and finish. Popsicles are provided just after the turnaround between mile 8 and 9; participants may indicate a flavor preference before the turnaround and volunteers will have it ready after. Port-o-johns are available at the start and finish only. Energy gels are not provided; participants must carry their own supplements.
At the finish there will be watermelon, bananas, and other refreshments. There are no awards, t-shirts, or finisher medals. The event is staffed by volunteers. In dangerous weather conditions the race directors may delay, cancel, or convert the event to a fun run; there are no refunds. Visit the organization's website for the most recent information.
