Green running events are races that prioritize environmental sustainability. These events often implement practices such as using eco-friendly materials for race bibs and medals, providing reusable water stations, and encouraging participants to use public transportation or carpool to the event. Additionally, many green running events support local charities and initiatives focused on environmental conservation. They may include activities like tree planting or clean-up efforts as part of the event, fostering a sense of community and promoting awareness about the importance of protecting our planet.
