All abilities welcome!
Not quite ready for the full marathon yet? No problem - we have something for everyone with the half and quarter distances.
One of our guiding principles with setting up Isoman was to make it inclusive, not only to elites, but to beginners alike and create a single day of endurance where individuals from the swimming, cycling, running and triathlon community can all come together and enjoy the sports we love.

Fancy a face off with your swimming or cycling buddies?
By taking the world records for the marathon, 10km swim and the UCI hour cycling record and applying a tiredness formula (Read More...), we have equalised the distances across the sports so that level of excellence required to acheive the same time is similar so for the first time ever, you can compete against swimmers and cyclists to find out who is the best athlete. This gives you the opportinity to challenge your swimming or cycling buddies to a race to see who's the best athlete, All events will take place on the same day - nowhere else will you get the chance for such a face off.
Most equal of Triathlon Relays?
Or better still get together with 2 of your friends and do the relay. Nowhere else will you find a race where the legs are more equal!
Sign up here for the Relay.
The course involves 1, 2 or 4 laps of mostly flat, traffic free Arrow Valley Park with nutrition and water stations accessible on every lap.
Chip timing will be available with valuable split time intervals for each lap!
Party In the ParkMake sure you pack your dancing shoes. We'll have music all day with live music at the main stage in the expo field from 2pm onwards to welcome the athletes competing in the Isoman home.
Come and enjoy a beer or two and party the afternoon away! It is saturday afterall so no work in the morning!
There will be bouncy castles and other activities for the kids to take part in, so bring them along too! Whether you're taking part, watching loved ones or simply want to come and see what it's all about, you're all welcome.
