The Isoman Triathlon

Game Changer Zone 3

30th June 2018 - Arrow Valley Park, UK (B98 0LJ)

All Profits for 2018 going to St Richard's Hospice

The Equaliser!

The best kept secret of triathlon is that it doesn't test you to the limit in all 3 disciplines....until now

In Isoman there is no where to hide.

Swim 7 Miles, Bike 61.3 Miles, Run 26.2 Miles

Harder than Ironman...Possibly?
Fairer than Ironman..Definitely!

Last Chance to race at this iconic race in the UK for a few years! After this year we will be concentrating on making the US and Australian events a reality so we will not currently be holding the 2019 UK event. We've got good numbers already for 2018 - but don't put it off until next year - unless you are willing to travel!

Voted game changer of the year 2016 by 220 Magazine readers.

Most triathlon events are biased mainly towards the cycling and to a slightly lesser extent towards the running. Iron distance pros for example will spend only 10% of the total time swimming, 54% of the time cycling and 36% of the time running. The aim of Isoman is to address this imbalance and create a triathlon for which all disciplines demand an equal level of excellence.
Pie Chart Pie Chart

The history of the first iron distance triathlon suggests that it was created out of a desire to see who was the fittest across the disciplines of swimming, cycling and running. They did this by bolting together 3 individual long distance events that existed on a particular island in the Pacific Ocean. They produced an amazing endurance event but never achieved their original goal!

To excel at Iron distance triathlon you must be an excellent cyclist/runner.

To excel in Isoman you need to be an excellent triathlete!

On Saturday 30th June 2018 in the heart of Worcestershire UK, centred at Arrow Valley Countryside Centre, we are running only the third ever Isoman triathlon event with the blue ribbon event being the full Isoman described above.

Be a part of the next chapter in the evolution of triathlon.

Isoman: Triathlon Equalized.

Want to know where the numbers come from?

Medal, Goody bag, T-Shirt and Party! And the chance to be part of this spectacular day of endurance! Note you must enter before 1st June to guarantee T-shirt medal etc.


All abilities welcome?

Not quite ready for the full Isoman yet? No problem - we have something for everyone with the half and quarter distances. Also, you can choose to do the event your way and pick and choose which distances of each of the disciplines you want to do. Or do them on their own!

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.

Single Discipline Events/Relays

These will take place throughout the day roughly in line with the triathlons, giving you the opportunity to compete in 1 or more of the disciplines - the choice is yours.

And because of the unique nature of our event, you will be able to compete with people doing a different discipline. So if your friend's a runner and you're a swimmer. Lay down the gauntlet and challenge him to fair duel!

If you have two friend's with different abilities then team up and do a relay! For the first time in triathlon, all legs of the relay will have an equal bearing on the result!

At the end of these single sport events we will put you all back together in a list and award a prize to the athlete who has the best time on any single event
