Looking for a feel good adrenaline rush? Be bold in the cold with a plunge into the Atlantic and/or winter jaunt around the East End to support the Natural Resources Council of Maine's work to reduce climate change pollution. The bone-chilling fun 5K and dip will take place at Portland's East End on Tuesday, December 31. The 5k begins at 11:00 and the dip will be at noon - the "warmest" part of the day - at East End Beach! A shuttle will return participants to their cars at Back Cove after the plunge.
