Calderglen Harriers Trail Races

View all races for Jun 2026

The Calderglen Harriers Trail Running Festival is an evening celebration of trail running in Calderglen Country Park, East Kilbride. With events ranging from a toddler dash and junior races through to 5K and 10K trail races, the festival offers something for runners of all ages and abilities.

The headline 10K extends through the trails of Calderglen Country Park and out towards Langlands Moss, while the 5K follows a faster route entirely within the park. Younger runners can take part in the Ewan Murray Memorial 3K Trail Race, the 1K Trail Race or the free Toddler Dash, creating a family friendly festival atmosphere throughout the evening.

Set among woodland trails and parkland scenery, the festival combines competitive racing with an inclusive community feel. Chip timing, fully marshalled courses and the popular Calderglen after race buffet help make it one of the standout summer trail running events in the area.
