6. Conclusion:

The summer of 2025 in the UK presents numerous opportunities for runners seeking to participate in marathon, half-marathon, and ultra-marathon events. England stands out as the region with the highest concentration of events across all three categories, particularly in the half-marathon distance. The data suggests a strong preference for half-marathons among runners, as they are the most frequently listed event type. While marathon and ultra-marathon events are also prevalent, they are fewer in number compared to half-marathons. Scotland and Wales offer a selection of events, catering to both road and trail running enthusiasts, while the data reviewed indicates a lack of organized events in these categories for Northern Ireland during this period. The concentration of events in England, especially half-marathons, could be attributed to various factors, including a larger population of runners, greater accessibility to organized races, or a more established running culture. It is important to acknowledge that the findings of this report are based on the analysis of publicly available data, and there might be other events not captured in the reviewed sources. Further research, potentially involving direct outreach to running clubs and event organizers in each region, could provide a more exhaustive list.
