Waste is a big problem in the events industry and endurance events are no exception. And it’s not only about water bottle waste. Sometimes the things we offer our participants, like medals and T-shirts, end up discarded or in a cupboard somewhere never to see the light of day again.Change may be just around the corner though. In today's episode we'll be hearing from Chris Zair on how UK-based Trees not Tees is helping race directors offer participants the option of planting a tree instead of (or often on top of) receiving the traditional finisher shirt and medal.It's a really interesting discussion with lots of details on how the Trees not Tees model could incentivize change in the industry through a win-win for participants and race directors alike.Things covered in this episode:How Trees not Tees was born from the frustration of trail runner, Jim MannThe Trees not Tees model: good for participants, good for race directors, good for sponsors, good for the environment.The economics of Trees not Tees: What does it cost for the race director to offer a tree-planting option?
