The race was a mere 0.8 mile dash around track and fell ending with a crazy climb of 28% to the finish line.
Starting at the finish, the route takes on a choppy descent followed by a relatively flat dash along the track before you scramble up the brutal ascent.
The winners of their heats will go through to the decider, where they ran it once more to become King or Queen of the Bincombe bolt.
All money raised is split between Dorset County Hospital Charity and Cancer Research UK.
There will be prizes for the top 3 in each category, and also for the best British themed fancy dress!
