ROC Race

Please note: This event has already occurred.
Running a 5K is a great way to get in shape. Running a 5K that includes a wrecking ball, moon bounce, rope swings and an inflatable slide? That's a recipe for "Most Extreme Elimination Challenge"-style mayhem and a good workout. The Ridiculous Obstacle Challenge 5K comes to the RFK Stadium grounds Aug. 10. Don't worry about posting a personal best: The event, which is open to anyone 13 and older, is untimed. Start times are hourly from noon to 5 p.m. Register online at www.rocrace.com/dc.
