Gallery: 2012 Reston Relay for Life

The football field at became part campground, part party and part carnival on Saturday at the 16th annual Reston Relay for Life to benefit the American Cancer Society.

More than 600 participants - many of them cancer survivors - on 59 teams kicked off the event with the mid-day opening ceremonies. Team members take turns walking around the stadium's track throughout the night. There will be a special Mother's Day breakfast and closing ceremony Sunday morning before the event concludes at 8 a.m.

In between laps, there were lots of ways to keep busy: a petting zoo from the Reston Zoo; "Rally for Life" tennis tournament; a silent auction; a moonbounce; live music; and lots of impromptu Frisbee and lacrosse action.

As of Saturday night, $181,133 had been raised.
