Starting from the high point of Crowborough, this 9.2km loop offers a quintessential Wealden running experience, blending steady climbs with fast, technical descents. With roughly 65% of the route on paved surfaces and the remainder following mixed woodland trails, you’ll need a versatile pair of road-to-trail shoes to navigate the 151m of vertical gain. The clockwise circuit takes you deep into the lush canopy of Crooked Wood and skirts the serene Hamsell Lake, offering a rolling "Hilly 3" intensity that provides a fantastic cardiovascular workout without being overly grueling for intermediate runners.
The High Weald is an Area of Outstanding Natural Beauty, and this route passes through the very landscapes that inspired A.A. Milne’s Winnie-the-Pooh, located just a stone's throw away in Ashdown Forest. Crowborough itself is the highest point in East Sussex, once used for iron smelting in the Roman and Tudor periods; as you run past Hamsell Lake, look out for the ancient "ghyll" woodlands—deep, steep-sided valleys carved by streams that are unique to this part of England. This area remains a quiet sanctuary for local wildlife, where it's common to spot fallow deer emerging from the treeline during early morning runs.
