Event overview
The stunning estate features Deer Park Mere and panoramic views across the hills.
This Cheshire castle has been home to the Cholmondeley Family since the 12th Century and its grounds feature Deer Park Mere which is a beautiful setting for the open water swim. To the south of the castle lies Tower Hill, the highest point of the run routes, where athletes are rewarded with panoramic views of the Beeston and Peckforton Hills.
Throughout the multisport weekend, athletes and spectators can enjoy a fun-packed festival village, right in the heart of the Cholmondeley Castle estate, featuring live music, shopping, food and drink, children’s entertainment, yoga and more.
This event is part of Cholmondeley Castle Triathlon and Multisport Festival.
