The Special Olympics Colorado Polar Plunge presented by Westerra Credit Union is a fun and unique way to help support a great cause. You can challenge yourself to jump into a frigid body of water (either a pool or reservoir) and get pledges of financial support from your family and friends. “Plungers,” as participants are referred to, may take the Plunge as an individual or as a team member. Many Plungers come in costume and stay afterward for the festivities or to cheer on other Plungers!
