Experience the tranquil beauty of East Hertfordshire on this flat, fast-paced 6km out-and-back route along the historic Cole Green Way. Since this path is entirely unpaved, runners can enjoy a softer, trail-like surface that is gentle on the joints while maintaining a consistent rhythm with zero hills to navigate. Starting from the edge of Hertford, you will head out through a scenic green corridor for 3km until you reach the bridge overlooking Birch Green Lane, where you’ll turn around for a rewarding 3km return leg. It is an ideal course for tempo runs, intervals, or a peaceful recovery session immersed in nature.
The Cole Green Way follows the former railway line that once connected Hertford and Welwyn Garden City, serving as a vital link in the Great Northern Railway starting in the mid-19th century. Today, this repurposed "rail trail" forms a crucial part of the Lea Valley’s wildlife network, offering runners a chance to spot local birdlife and flora away from the noise of traffic. Running here feels like stepping back into the area’s industrial past, as the straight, level gradients designed for Victorian steam engines now provide the perfect natural stadium for modern athletes looking to hone their speed and endurance.
