The Bright Skies is a thrilling day time trail half marathon, 10 Mile and 10K race (with canix races), as well as a 1K/2K kid’s race for 3-12 year-olds. Bright Skies was born off the back of the Dark Skies event (part of the Wild Night Run Series), after several people said they loved the route but would like to see some of it!

It follows an undulating yomp through Surrey’s muddy, rolling hills in Dorking. Passing through the Denbies Estate in the Surrey Hills, this is our fifth event at Denbies and we love it here. This year, entrants will make a contribution towards Shower Box - who provide hot showers for homeless people in London - and we will be working with some additional event partners.
