Once again, we are delighted to bring you the Green Lion Award in recognition of innovators in environmental sustainability for running/racing events. The races below are events nominated to The BibRave 100 that have integrated sustainable practices into their race operations, reducing the carbon footprint of their event. Some examples include recycling and composting; sourcing recycled swag and local, organic food; reducing waste and donating leftover materials; and providing tap water instead of small plastic water bottles. These races have made environmental sustainability a priority not just for 2020, but consistently over the past decade and we applaud them for their efforts to protect our planet.
