While triathlons are frequently called the new marathon for  endurance athletes, no matter how many different locations you go to do one, the race is basically the same.

The organisers of the SUPBikeRun decided to take a traditional triathlon and turn it on its head.

The SUPBikeRun is part stand-up paddle boarding, part mountain biking and part trail run.

The race’s first year in 2014 saw huge numbers of people joining up to give this new event a good go. This year’s events, spread over much of the UK’s nicest countryside, are expected to be even better.
