Race Information
Come run or walk one of the many race distances and feel good about supporting the environment. Each finisher will receive a native sapling tree + an additional tree will be planted. Over the years at the Earth Day events, thousands of trees have been handed out that grow and sequester more and more carbon each year. On top of all that, there will also be recycling of old running shoes, so don't forget to bring them so they can be donated to Africa via the More Foundation Group. Tell your friends and come out for this great event!
