On Saturday morning, Rock 'n' Roll Marathon runners will race past  the Lincoln Memorial, across the Memorial Bridge, through Columbia Heights and Dupont Circle. And at every mile along the course, the 30,000 participants will be treated to motivational jams.

Yes, they take their "rock" moniker seriously. Thirty-five local music acts, ranging from surprisingly awesome/adorable pre-adolescent rockers Throwing Wenches to fierce lady-led drum corps Batala will dot the course, strumming, thumping and yodeling for the enjoyment of runners-by.

Tomorrow's weather is likely to be uncomfortably soggy, but Dan Cruz, a spokesman for the race, assured us that, like the race itself, the shows will go on; the 26 stages along the course will be covered by tents, making the drizzle an issue only for the runners. Want to imagine what sounds will blare from the corner of Harvard and Fifth streets NW at 9:30 a.m. as the competitors blaze past?  Just check out videos from a few of the acts:
