Tackle a unique long-distance endurance challenge with this 29.9km loop through Bristol’s diverse landscape. This route offers a captivating mix of fast, flat tarmac and technical riverside trails, boasting a surprisingly gentle 75m of ascent. You’ll start by powering long the iconic Bristol and Bath Railway Path, highlighted by the atmospheric mile-long Staple Hill Tunnel. As you transition away from the hard-packed cycle ways, the terrain shifts into more natural territory along the River Avon. Runners should be prepared for varying surfaces, as the scenic woodland and meadow sections can become wonderfully muddy after a typical West Country rain, making trail-specific footwear a wise choice for this near-marathon distance.
The route is steeped in Bristol’s industrial heritage, following the historic veins of the city’s transport past. The Bristol and Bath Railway Path was the first major project of Sustrans, transforming an old Midland Railway line into a green corridor. As you reach Hanham Lock, you’re hitting a classic local landmark where the river’s history comes alive. The untimed section here is a nod to the local "run-to-the-pub" culture—allowing you to soak in the views of the lock with a quick refreshment before navigating the final urban stretch back into the heart of the city. It’s a perfect showcase of how Bristol seamlessly blends its rugged natural beauty with its vibrant, bustling city center.
