The Hardmoors 55

The Hardmoors 55 is a 55-mile ultramarathon from Guisborough to Helmsley, traversing the North York Moors and the Cleveland Hills. About 95% of the route sits on the Cleveland Way National Trail, with over 2700m of ascent and potentially wintery conditions. Runners pass through a sequence of checkpoints (6.5 to 53 miles) offering basic food and water, plus a compulsory tracker.

The race is designed to be run unsupported, with strict kit checks and penalties for missing items. A single support runner is allowed from Sutton Bank to the finish. Drop-bags and coach transfers are available, with a 16-hour cut-off. Visit the organization's website for the most recent information.
