Meet the organiser

The Race Organiser creates outstanding opportunities for people to bring out their best run, swim or cycle performance. We seek out the most inspiring and rewarding locations, develop race routes and event formats, and create a brilliant atmosphere and race day experience – offered at the best possible value. We don’t think it’s ok to ask people who are aspiring to do amazing things to pay huge sums of money, so we charge as little as we can afford, rather than as much as we can get away with.
