Course and race information

The out-and-back course runs along the Huddersfield narrow gauge canal and reaches Tunnel End, a 3.5 mile tunnel under the Pennines. The organiser provides water and feed stations approximately every three miles and aims to be cup-less, so participants are asked to bring a reusable cup or bottle. Marshals are positioned on the course and runners should notify the nearest marshal if they are injured or need to retire. There may be unmarshalled road crossings.
