The only marathons I have been a part of involve 12 episodes of Law & Order aired back to back and the loss of sensation in my buttocks. Another type of marathon is being covered tonight on PBS and it doesn’t involve a dozen hours of Sam Waterston. Tonight’s episode of NOVA is called the Marathon Challenge and follows 13 novice runners as they train to run the Boston marathon. I’m really looking forward to watching this because…I signed up to run a half marathon! Woo-hoo! Me and the Indianapolis 500 Mini-Marathon on May 3, 2008, baby! I’ve lost half my weight, I wrote a book called Half-Assed: A Weight-Loss Memoir and now I’m going to run a half-marathon. I hope to learn a lot from this show and I hope no one gets horribly injured or collapses in a pool of vomit because that registration fee is non-refundable. Check your listings for time and station.
