The event takes place annually in Belfast, Northern Ireland, typically in early May, and features a course that traverses all four areas of the city: North, South, East, and West. The route starts at Stormont Estate in the east and finishes at Ormeau Park in the south, covering a standard marathon distance of 42.2 kilometers (26.2 miles).\n\nParticipants run on paved city roads in a single-loop course with a rolling hills profile, which introduces varied elevation but no major sustained climbs.
