Event overview

Brought to you by the largest triathlon organiser in the UK!

An epic challenge to complete a 3.8km swim in the meandering river Ouse, a 180km cycle around the scenic Cambridgeshire countryside and finish off with a 42.2km marathon around the beautiful town of S St Neots or the half distance which is a new addition!

Along the way you will overcome both physical and psychological challenges that you have never previously experienced and once completed, you will stand tall in the knowledge that you have completed your own personal Odyssey.

The Odyssey course is the ultimate in spectator-athlete interaction with multiple opportunities to cheer on the athletes in each of the three disciplines, including the ‘tent of enlightenment’ that the runners will pass through on each lap of the run.

This event is open to everyone, regardless of ability and there will be plenty of activities at the venue to keep the whole family entertained while you race.

Really great event! The river swim was very pleasant, the bike course is interesting, and the run course is as flat as can be. A pb potential course. Superb value for a full distance event. Brian H

The Odyssey is the next big thing to hit the irondistance stage. Super appreciated the atmosphere created by the ATW team, super friendly and welcoming. Would strongly recommend this event to new and seasoned iron athletes. Lewis S

Brilliant event that will only continue to get better. Good location and the swim, bike and run courses were all suitable for first timers and the more experienced triathletes. Loved the event village, great atmosphere and super friendly and helpful marshals. Will definitely return. Craig D

I did the bike leg of a relay team. Loved the Odyssey. Great atmosphere throughout. Loved the bike route which involved 2 laps with out and back sections allowing you to see how you were doing against others. Would recommend! Lem L

This was my first long-distance triathlon...  river swim is good, bike course nice and fast and good for spectators, and the run course is excellent in the park along the river with 90% tarmac and some small sections of grass, not boring and pleasant. Moise C

Brilliantly organised event. Marshals we’re fab and the run course was lovely and scenic but most importantly flat 😊 The party tent also a great idea and really gave me thay much needed boost when running through it each lap. Danielle H
