MKB NY Marathon for Children's Health Foundation Fund

I'm running the NY marathon in November - my second marathon this year and second one ever. For this one, I'd like to run for a cause and I've decided to raise money for the Children's Health Foundation. Running has become a passion (read: obsession) of mine over the past few years and I attribute a big part of the reason I got into the sport down to the flexibility Pinterest has offered me. As you probably know, Pinterest matches donations up to $1,000. Any donation big or small would be greatly appreciated and will effectively be doubled!
