Sacramento Brain Freeze

Saturday, November 4, 2017, Nimbus Dam Recreation Area

Welcome to the Sacramento Brain Freeze, an event to raise awareness and much-needed resources to fund critical brain tumor-specific programs to improve the lives of all those affected by brain tumors. Hosted by the National Brain Tumor Society, the Sacramento Brain Freeze is a polar plunge style event that offers individuals and teams a chance to honor and remember loved ones, connect with others interested in the brain tumor cause, and helps to educate the local community on the diverse needs of the brain tumor community.

Teams and individuals are encouraged to wear their best costumes, bring all the spirit they have and get ready to plunge into Lake Natoma in celebration of all their hard work of fundraising for this urgent mission.

Online Registration has closed. If you want to attend and participate in the event, please arrive at Nimbus Dam Recreation Area at 10:00 on event morning. We’ll see you soon!

You’re invited to join us at the 1st Annual Sacramento Brain Freeze by registering today and freeze with us at Nimbus Dam Recreation Area on Saturday, November 4, 2017!


Due to the devastating fires our Northern CA communities have recently endured we will have a gift card drop off on event day. Feel free to bring gift cards to donate in the amount of your choice and we will be sure to get them to families in need.

Earn fundraising prizes!
