Loved reading your dad's post. I got into running 2 years ago and now have 3 5Ks under my belt (no marathons yet, but it's a good start for me). Last Christmas my mom and my aunt gave me some of my grandpa's old running medals. I've been wanting to do something special with them and it looks like this might be a nice option. They weren't for full marathons, so I don't know if they'd be of interest to your dad, but if so, I'd like to pass on one or two for such a great cause.
