I've been doing the M4M thing for almost 15 years, and for most of those years I ran the Boston Marathon. However, due to a few injuries, I've downsized (to use a real estate term) to the half marathon for the past couple of years. I wish I could tell you which one I'm running this spring, but as of now I have no idea. But I guarantee you, I'll run something. I haven't retired from marathon running, though, and am registered to run the Chicago Marathon this fall. Nevertheless, I'm dedicating all of my spring races to the deserving patients of CVIM. I hope you'll join me by contributing generously to this amazing organization.
