Run Aintree Half Marathon, 10k & 5k October 2027

The Run Aintree Half Marathon, 10K & 5K is a road-running event taking place in October at Aintree Racecourse in Sefton, United Kingdom. Participants can select a 5-kilometer, 10-kilometer, or half marathon (21.1 kilometers) distance, accommodating newer runners, those preferring shorter distances, and individuals targeting a longer race. The primary attraction is the location: the races utilize the well-known Aintree racecourse, more typically recognized for horse racing than large-scale running events. Liverpool Running Events manages the series. The setup is straightforward: three standard distances at a single venue, with the racecourse environment providing a distinct local character.
