A 12 ml multi-terrain run on the western edge of The Cotswolds in Gloucestershire, England. A testing alternative to the official Dursley Dozen run on the 2nd Sunday in February every year - now in its 15th year. My alternative has much of the same charm and attractions - mud, water, forests, steep climbs and great views. Alas, it lacks the rope climb at The Precipice which is a charming & challenging feature of "the real thing". Enjoy.
