A Polar Plunge is a fundraising challenge made to an individual or group challenging them to dive into a cold body of water in order to raise money for Special Olympics. Each participant collects pledges from family, friends and businesses in the hopes of raising lots of money for the local Program. Then,they "take the plunge" in the cold water to benefit Special Olympics.

The Polar Plunge is a very popular special event among Law Enforcement Torch Run volunteers across the country. Approximately 24 Polar Plunges take place every year in 15 U.S. states, helping to raise millions of dollars for Special Olympics Programs.
