The Isoman Speeds Cycle

1st July 2017 - Arrow Valley Park, UK (B98 0LJ)

Isoman Speeds Cycle

Take on the Isoman Speeds Bike Time trial (or sportive).

Take on the beautiful rolling hills of Worcestershire...Take on the Cycling "Marathon":

By using the UCI hour cycling record and comparing it with the world record for running a Marathon (currently just under 2 hours and 3 minutes) we have predicted how far a world class cyclist would get in the 2 hours and 3 minutes. So, on the road, without drafting and with some account of the terain, the answer comes out to be 61.3 miles. (Read More...) So to put it another way, we reckon that 61.3 miles of our course is roughly equivalent in terms of the level of excellence required to acheive a similar time when compared to the runners marathon of 26.2 miles.

Medal, Goody bag, T-Shirt and Party! And the chance to be part of this spectacular day of endurance!

All abilities welcome!

Not quite ready for the full "marathon" yet? No problem - we have something for everyone with the half and quarter distances. Also, you can choose to do the event as a time trial and have your time entered for the best of the day. Or if you want to simply go out and enjoy yourself you are also welcome to cycle in groups.

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.

Or do as a sportive?

You additionally have the option of doing the half and full distance bike rides as sportives. This means you can ride in groups of 5 or less around the course. You will not be able to compete for best athlete by choosing this option, because you can effectively draft. However, all profit raised from these options will be going to our charity partner Bloodwise. See below for more details.

Fancy a face off with your swimming or running buddies?

As we believe we have equalised the three disciplines of running, cycling and swimming (yes, we've done a similar thing with swimming too!) in terms of the level of excellence required to acheive a similar time, 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.


Each of the 3 courses is single lap (with some overlap in the course) with a nutrition and water station available on the full. This is a fast and beautiful course that takes into account the rolling hills of Worcestershire.

Chip timing will be available!
