The Man versus Horse Marathon is an annual race over 22 miles (35 km), where runners compete against riders on horseback through a mix of road, trail and mountainous terrain.[1][2] The race, which is a shorter distance than an official marathon road race, takes place in the Welsh town of Llanwrtyd Wells every June. There are other Man versus Horse races — in Scotland based at Dores, near Loch Ness,[3] in Central North Island, New Zealand[4][5] and in Prescott, Arizona.[6][7]
