Disney darlings the Jonas Brothers already have to elude legions of fans trying to get close to them, so it's fitting that singer Joe Jonas would tether this rabid support into a charity event. This Labor Day, September 6, supporters can take part in the Joe Jonas iWin 5K Fun Run/Walk taking place on the main campus of Nova Southeastern University in Davie, which is home to the Broward County chapter of the Florida Special Olympics. Register here, and start raising money for the Special Olympics for a chance to drip your sweat on a real, living Jonas. The Brothers perform September 7 at Cruzan Amphitheatre in West Palm Beach.
