The Greensand Marathon Dorking - Westcott - Coldharbour - Leith Hill - Somerset Hill - Holmbury Hill- Pitch Hill - Reyards Hill - Winterfold Hill - and back again!

This race will not be doable without the support of LOADS of marshals! Please consider coming along to help out, either at the race HQ, race start/finish or out on the course. We will need around 40 marshals - every little helps.

All marshals receive the race shirt, a hearty cooked breakfast back at the HQ, and our eternal, undying thanks.

Marshals can also elect to receive a free place in a future Trionium race.

Please email for details, to rob at trionium dot com. THANKS!
