The Gebert-Arbaugh Polar Bear Challenge is an annual cold plunge event where individuals and teams commit to plunging into the frigid waters of Lucky Peak Reservoir. The event is open to all who are willing to brave the cold for a great cause. Participants often wear costumes, bring team spirit, and raise money through sponsorships.

The challenge is traditionally held in early January at Lucky Peak Reservoir, just outside of Boise, Idaho. Participants register in the morning, enjoy the pre-plunge festivities, and take the plunge late morning or early afternoon.

The Polar Bear Challenge is a peer-to-peer fundraising event benefiting Make-A-Wish® Idaho (MAWI). Participants collect donations from friends, family, and businesses in support of their brave dive into the cold water. These donations help grant life-changing wishes for children with chronic illnesses across Idaho.
