A 54 km (34 mile) ultra in the North York Moors with around 1,400 m of ascent. The route uses moorland trails, forest track and open sections that can be exposed, with climbing accumulated through repeated rises rather than a single sustained climb. Underfoot conditions can vary between firm track and softer trail depending on weather. Navigation, checkpoints and aid station detail should be followed from the organiser’s official event page.
