Starting at Leigh Court, you will head into Leigh Woods along smooth trails. The 10K does the same loop as the 5K course, plus a loop that goes south and deeper into the woods.

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.

    Did the 5K Trail Race in 2020

    I enjoyed it, but it wasn’t so clear where to go - some 5k runners did 4K, some did 6k, there were few signs and not really enough Marshalls. It was fun tho, liked the fire pits and the snacks at the end, so thanks.
