Registration for the 2017 Portland Polar Plunge is now open! As a "plunger" you register to participate in one of the five plunges around the state. Maybe you join a team. Maybe not. Then you raise a minimum of $50 in pledges from friends and family (but the more you raise, the bigger your incentive prizes). Then on plunge day you run or jump into the water and get out as fast as you can. You decide how far you want to go in. It's all done for fun and to raise money for a great cause.
