I completed a beautiful six mile (nearly) route in Kilburn woods on Monday, route details here:
For those who haven’t tried it, the first mile is fairly easy going, through the woods which then open out with good views across to Sutton Bank. Then the hills start, gently at first but after a shortish flat section the main climb. There is then a beautiful if sometimes muddy path beneath the limestone cliffs, and another short incline before arriving at the foot of the Kilburn White Horse:
From there it is a short descent by road or path and then back on an undulating forest track to compete the loop.
In good weather it is beautiful, and in bad weather relatively sheltered. The changing seasons bring dramatic changes to the woods and surrounding countryside. It is especially good around sunset when the cliffs turn a golden colour. In running terms it is challenging but not too difficult. Highly recommended!
