The 10th anniversary of one of the UK’s best duathlons and arguably toughest events takes place on Saturday 24th April 2010 over the 12km off-road undulating run, 40km hilly/rolling bike and 4km flat out-and-back run.

The event is the first event in the blueseventy multi-sport series with significant cash prizes up for grabs as well as the fourth race in the British Duathlon Ranking Series.

Over the years some of the UK's and World's best duathletes have conquered this tough course set in the heart of the Peak District, whilst many more have failed. Previous winners include Tim Don, Will Clarke, Catriona Morrison and the late legendary Benny Vansteelant.
