The Clumber Park Duathlon is the perfect event for testing out your fitness post festive celebrations and even help to shift any extra unwanted Christmas pounds!

The duathlon is set in the picturesque setting of one of Nottinghamshire’s finest National Parks and is perfect for all abilities. In previous years, it has attracted first timers along with Great Britain age-groupers.

The event is split into two distances; a sprint and a standard distance but which ever one you choose to take part in will see you race through acre after acre of beautiful woodland. The run sections take place on fully closed tarmac roads and features steady climbs at the beginning – but don’t worry, this means you will be running downhill to the first transition.

The bike course is through some of the most beautiful tree lined routes in the UK, including some closed roads. The long rolling roads will test your strength as the roads pitch from climb to descent.
