The Urban Dare adventure race returns to Denver Saturday, as teams are challenged to a variety of activities across Denver, from a photo hunt to answering trivia questions. Each team (made up of either two adults or a three- to four-person family) will receive 12 clues that will lead them to checkpoints around the city. Teams can hit checkpoints in whichever order they choose, but they must arrive at them either on foot or via public transportation. (This year's course will cover approximately five miles.) Teams need a digital camera, a map, and something with which to take notes. Even better? Teams are allowed to "cheat"---that is, they can use smart phones or call friends for help. The race starts at noon at Pat's Downtown Bar and Grill, 1624 Market St. Registration opens at 11 a.m. and costs $50 per person, with all proceeds going to breast cancer research. Bonus: Urban Dare used to require that teams wear T-shirts, but this year participants can don costumes if they prefer. A prize will be awarded for the most creative effort.
