2024 San Mateo County Polar Plunge

Frequently Asked Questions


How much do I have raise to participate?
Plunger/Chicken - All participants must raise a minimum of $125 and will receive a cool Polar Plunge t-shirt and brunch.  Raise additional funds and you can earn more cool stuff based on the amount you raise!

Is this a swim?
Absolutely not. Participants run into the water, frolic around for a minute or two, snap photos, then out of the water we go!

How far do I have to go in the water?
That is completely up to you! Dip your whole body or your big toe, whatever you decide is fine by us!  If you don’t want to get wet at all, register as a chicken. You’ll be excused from plunging but qualify for the same incentive rewards as our Plungers. 

Do I have to dress in costume?
Heck no! But don’t be surprised if the majority of participants will.  If you’re part of team, get in the spirit of things and come up with a team theme. 

What should I bring to the Plunge?
You will want to wear some type of water shoe. Don’t forget to bring a towel and a change of clothes too!  Some type of plastic bag or backpack to put your wet clothes will probably be a good idea.

Is there a minimum age requirement?
No, anyone is welcome to join us. However on Plunge Day, those under the age of 18 must bring a Polar Plunge waiver signed by a legal guardian. No waiver, no Plunge, no exceptions! 

Do spectators have to pay to watch?
Nope! Your cheering squad is more than welcome to come and watch the festivities free of charge. Really, they gotta see it to believe it!
