Kit List

Please note that head torches are compulsory. This is due to the fact that although parts of the route are illuminated, runners will be running through some dark areas. Reflective or fluorescent clothing would also be useful.


Spectators are more than welcome at this event and it is a great evening out for the family. The sight of several hundred head torches twinkling through the dark is not to be missed.


This event is made possible by the fantastic volunteers, who help with marshalling and race set up.
