Odyssey SwimRun -
Now Ötillö Swimrun USA

Odyssey SwimRun was America's original SwimRun organiser.  As stated on their original 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 owned by Aaron Palaian of Odyssey, promoting the sport of swimrun; Aaron's main goal was to remember his car plate number - but promoting the sport is an added bonus!

In Odyssey events 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 races in North America.  In some of the races there is also now the option to enter a solo event.

Odyssey Swimrun Events

Below you can find details of Odyssey (now Otillo Swimrun USA) events:


Date:  July 7th, 2024

Venue: British Columbia, Canada

Set in the mountains of BC, two hours north of Vancouver, Whistler is a famous resort, for good reason. Here the swimming sections are across cold glacier-fed lakes. The running sections take in roads, single track trails, jumping off docks and some rock scrambling.

The water temperatures can vary between 12C and 16C, while air temps at this time of year range from 11C to 27C - that's a BIG range!

There are THREE events on offer, and you can take part either as a SOLO racer or as part of a team of 2; the World Series races are the longest. The Sprint distance os more maneageable for most of us, and the Experience distance is the shortest, giving you a taster of this sport. The swim to run ratio varies from 1:5 for the World Series race, to 1:4 for the Sprint, and down to 1:9 for the Experience.

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.

2024 will be the event's 8th year and the organizers say it is 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.

Mackinac Island is as rich in history as it is in beauty. Located just northeast of the Mackinac Bridge In Lake Huron, Mackinac Island offers a unique opportunity for both family and friends to experience race weekend like never before.

Mackinac City's downtown area offers a variety of things to do for people of all ages and trails and waters around this pristine island offer a vast playground for SwimRunners looking to stretch their legs on a new course that's challenging and breathtakingly beautiful.
