Odyssey Rat Race: June 15, 2024

All events are subject to Coast Guard permit approval.

We’re thrilled to announce that the Odyssey Rat Race will return for a third year. After 51 participants joined us for the inaugural Odyssey Rat Race, we are expecting a larger field and will make some exciting additions and changes to the event for 2024.

The Odyssey Rat Race is a special 3k (1.86 mi) in Marin County. The course starts from McNears Beach, goes around a buoy, and then run parallel to shore to Rat Rock Island, and then all the way back to McNears Beach.

Swimmers are provided with official times and winners are announced at the conclusion of the race, where swimmers and their families are invited to join a picnic lunch, with food provided for free for all participants. The Odyssey Rat Race is open to all experience levels, and no membership is required. Any swimmer comfortable swimming for two miles is welcome to participate

Registration is $75. All participants receive:

  • Official race T-shirt

  • Silicone swim cap

  • Official race time

  • Lunch!

Register below. Space is limited!

2022 & 2023 Odyssey Rat Race

The first Odyssey Rat Race was held on August 20, 2022, and it was a fantastic event!

We would like to thank our coaches, paddlers, organizers, and of course, the 51 athletes who competed in the event! We are currently finalizing times and acquiring additional photos from the event.

Thankfully, the swim ended up happening on a warm and sunny day, with some wind picking up halfway through the swim. All 51 swimmers successfully completed the swim. The swim started at McNears beach, went out around a buoy, and headed parallel to shore to Rat Rock Island and all the way back to the beach. “We are already getting excited about doing it again next year, bigger and better,” says Odyssey Founder Warren Wallace.
