Event overview

Whether you're new to your chosen distance, or a veteran, the team will cheer you along your way!

The 6-hour event starts at 9am or the 4-hour event starts at 11am.

The location is pretty self-contained, making this an intimate event and having exclusive use of the main area with plenty of open space. There will be a water, aid station located at the lap point so no stress of having to carry lots of food, water or equipment.

There will be a bespoke medal for the event, which you will receive at the end of the race. Or if you choose the 'green' lucky dip option, you will choose from a selection of previous medals.
