2025 Environmental Report
Event-by-Event Breakdown & Intensity
The following table details the emissions profile for each event.
Most Efficient: The Great North 10k (0.06 kg/participant) proves that mass-participation events can be delivered with a minimal food & drink footprint by using mains water. Highest Intensity The 13 Valleys (4.44 kg/participant) and Beyond Series (1.27 kg/participant) are significantly higher due to the provision of the ample aid station provisions (cheese, meats, hot meals) required for long-distance events, rather than simple hydration.
