Eco-friendly marathons are running events designed to minimize their environmental impact. These races often use sustainable practices, such as reducing plastic waste, providing recycling stations, and using biodegradable materials for race supplies. Participants are encouraged to bring their own reusable water bottles and are often offered plant-based food options at aid stations. Additionally, eco-friendly marathons may support local communities by partnering with local businesses and promoting sustainable tourism. Some events also contribute to environmental causes, such as planting trees or supporting conservation efforts, making them a great choice for environmentally conscious runners.
