On Saturday, August 31st, up to 300 teams of two will hit the streets of Washington, D.C. to play Urban Challenge, an original new adventure race that puts to the test how well participants know D.C.

A cross between road racing and a treasure hunt, Urban Challenge requires teams to decipher clues to twelve hidden checkpoints throughout the city that they must visit--and be photographed at- -in correct order before racing back to the finish line.

There's no established race course . . . strategy is everything as teams plot the fastest way to get to each checkpoint on foot and/or by using Metro lines or buses. Along the way, they keep an eye out for the elusive UC Skip Man and use cell phones to call for help with the clues. A lightning trivia round kicks things off in a daylong adventure that leads to a chance to compete for $50,000 in the Urban Challenge November national championships in Las Vegas.

Washington D.C. is the 15th leg of Urban Challenge's inaugural twenty-city tour of the United States. Game founder Kevin McCarthy developed the unique road racing adventure from a game he created for his daughter(1)s 12th birthday. "We had Kate and her friends racing all over town taking photos and solving clues. The entire day was such a blast, that I decided we had to come up with a way to let more people in on the fun."

Urban Challenge will begin at 8:00 a.m. on Saturday, August 31, at The Front Page Bar & Grill, located at 1333 New Hampshire Avenue, NW (between New Hampshire and 19th street) in D.C. The event is open to the public.
