Upcoming Events: 

We hosted the Castle & Derwent Triathlon event at Derwent Reservoir for a few years until 2023, when we joined forces with Wild Deer Events.

This year's triathlon is on 12th July 2026, organised by the fantastic Wild Deer team again. 

Wild Deer also organise run and swim events from Derwent Reservoir, as well as many other events in the North East! You'll find information about future events on their Event Calendar.
