Happy Valley Trails Event

10K and Half Marathon Races

The Happy Valley Trails event was established in 2022 as a running event in the hills and valleys surrounding Bollington. Locally the event has started to build a reputation for being at the more arduous end of the difficulty spectrum.

Make it your next challenge!

Next Event: Sunday 10th May 2026


Half Marathon Route
Not your typical half marathon! Approx. 770m total ascent over Kerridge ridge and Sponds Hill followed by a real sting in the tail up White Nancy! Mixture of farmland, rocky descents and beautiful woodland. Two aid stations on course. Typically takes 30 minutes longer than a flat course.
 
10k Route
Same start and end as the half marathon. 390m of total ascent including White Nancy and Kerridge ridge. One aid station on course.
