Festival of Endurance – 3 & 4 July

The Festival of Endurance is returning once again to Hever Castle combining a variety of swimming, running and cycling events. Taking place on Saturday 3 July and Sunday 4 July, the Festival of Endurance is organised by Castle Race Series.

View the competitor guides and see course maps.

Access for Hever Castle & Gardens Visitors – The Festival of Endurance starts at 5am and will continue throughout the day. The swim is in the Lake and river. Transition takes place on Lake View and some of this area will be restricted. Cyclists and runners will be in the grounds during the day but due to the limited numbers of competitors and their varying abilities this is unlikely to impact your enjoyment of your visit. Archery lessons will be available as normal.

Boat hire will not be taking place on the 4 July due to the weather.
