The “Becoming a Sustainable Runner Sustainable Race Series” offers a comprehensive guide for putting on environmentally friendly races. Mirroring the structure of race training, the series is divided into four parts – base, build, peak, and taper – which will equip participants with the knowledge and tools to host sustainable events. Led by Tina and guest experts, the live webinars provide insights, advice, and practical strategies gleaned from their experiences in sustainable racing. Participants receive recordings, transcripts, and a toolkit containing materials which will take care of most of the work for them. While attending all four sessions is optimal, the structure of the series emphasizes the importance of a strong foundation and realistic expectations in sustainability efforts.
