Castle Howard Triathlon routes

A swim of the Great Lake in view of Castle Howard itself sets up the grandest race of the Series. 

A short run up the North Lawn, pitches competitors out onto the hilly cycle which circumnavigates the 10,000 acre Howard estate, passing through the equally stunning Hovingham Estate, before touring most of the remainder of the Howardian Hills.

Probably the best of the Gauntlet cycle routes, this is one for the two wheel kings.  A circuit awaits on the run taking in all the key landmarks and monuments including the Castle South Lake and Lawn, The Atlas Fountain, the Temple of the Four Winds and the Mausoleum. 

Not for the feint hearted this is a true test of grit in an absolutely magnificent setting.
