As runners we run on the Earth almost every time we lace up our running shoes. On this day, take a moment to cherish the land that you are running on. We should also, as runners leave no trace behind when running. Throw out your gel packets on your long runs, recycle your water bottles, and donate your shoes to someone who needs them. Learn about the land. Find out ways you can make the Earth a greener place. Check out www.earthday.org for more information.
