Odyssey SwimRun -
Ötillö Swimrun USA

Odyssey SwimRun is America's original SwimRun.  As stated on their website:

“Swimrun is the fastest growing sport in the world. You participate in teams of two, alternating between trail running and open water swimming along a marked course.”

Odyssey was acquired by Ötillö in 2023, and is now run as Ötillö Swimrun USA.

Below is a cool car registration plate promoting the sport of swimrun; Aaron's main goal was to remember his car plate number - but promoting the sport is an added bonus!

The usual swim aids are allowed - hand paddles, pull buoys, wetsuits - and any hydration and race fuel must be carried throughout the race.  It can make a real difference having the right team mate and equipment as you can find out reading other pages on this site!

Odyssey SwimRun are entering their fifth year in 2024 with Ötillö Swimrun USA, and are once again presenting the only island-to-island style race in North America.  In some of the races there is also now the option to enter a solo event.

Casco Bay SwimRun

DATE:   Sunday, August 11 2024

VENUE:   Casco Bay Islands, Portland, Maine

The Casco Bay Swimrun is also known as the Cole Classic in memory of co-founder Jeff Cole.  This is America's original Swimrun event.  Odyssey Swimrun (formerly Swimrun USA) brought this exciting sport to the states.

2020 was the event's 4th year and the organizers say was set to be the best!  The east coast is stunning with a course full of amazing bay views and historic buildings and forts.

Be prepared for a variety of terrain from trails, grass, pavement and slippery boulders when the tide is low, together with cool, crisp salt waters!  Currents can be strong with choppy water and sea swells.

Jeff Cole - Swimrun USA & co-founder

From the organisers - about Jeff Cole:

"A husband, a father, a sportsman, an event organizer and a leader, Jeff Cole cared deeply about each and every person he had contact with. He grew up on the water and worked as a lifeguard and was a volunteer fireman at the Kennebunk Fire Dept for over 20 years, founded and produced multisport races – from the Fireman’s Tri in Kennebunkport to White Mountains Tri in Franconia, New Hampshire.

He served on the Board of Directors for numerous businesses, schools, and sporting organizations and yet spent a few weeks each year living off the grid completely self-sufficient. Jeff was an independent thinker but also a consensus builder. He never asked anyone to do something he was not prepared to do himself.

He is fiercely missed but his legacy lives on through his wife Kim, daughter Rachel, son Ben, his friends and through the SwimRun USA events he pioneered."

There are no vehicles allowed on the island. Your legs, bikes, and horses are the modes of transportation after you take the ferry from the mainland to get there.
