Hillsborough Castle & Gardens Running Festival

The Hillsborough Castle & Gardens Running Festival, presented by Gateley, takes place in the scenic grounds of Hillsborough Castle, Northern Ireland, on July 26, 2026. Offering both a 10K and a half marathon, the event features a picturesque course starting within the castle grounds, extending through surrounding forests, and passing historic sites like Hillsborough Fort and Hillsborough Lake before returning to the castle for the finish. The race includes mile markers, pacers, chip timing, and post-race goodies.

Participants enjoy a lively event village with food, drinks, and free race photos. Group bookings and optional technical t-shirts are available, making it a well-supported and family-friendly running event. Visit the organization's website for the most recent information.
