I found out about this charity on MCM website and remembered reading about it in Runner's World Magazine. I am running for this charity because I can believe in what this group is doing and I wanted to helps support them. Here is a description of M4M from their website: Medals4Mettle (M4M) is a non-profit organization that facilitates the gifting of marathon, half marathon, and triathlon finishers’ medals. Runners from around the world give their hard earned medals to Medals4Mettle. Our worldwide network of physicians and volunteers then awards these medals attached to a Medals4Mettle ribbon to children and adults fighting debilitating illnesses who might not be able to run a race, but are in a race of their own just to continue to live their life. It is in honor of this mettle and courage in bravely facing these challenges that they are awarded a medal.
