Assessing the Ecological Impact of Ultramarathon Events in Protected Natural Sites: ‘Le Grand Raid Réunion’

Outdoor sport events evidently have an impact on the environment. If they are taking place in naturally protected areas this impact is even greater. By taking ’Le Grand Raid Réunion’, an international ultramarathon annually organized in the heart of an UNESCO World Natural Heritage site, as a case study, this paper concentrates on assessing the ecological impact of an outdoor sports event in a protected natural site. On the basis of datasets taken from official logistics lists and from a survey conducted among all event participants the analysis embraces ecological and carbon event footprinting. Measuring those two indicators allows identifying the specific event-related ecological impacts, including diverse variables caused by the athletes, the spectators, and the related organizational requirements. The results of the study thereby have the ability to strongly influence the future event policy and to function as a model for the assessment of the ecological impact of other outdoor sports events.
