Without a doubt, the experience of training for, then running a marathon has changed me. In the past, even in my most devoted running times, the second the weather got cold, I'd go right ahead and slack off. I'd pretty much hibernate all winter.
Last night, it was freaking cold outside, but I bundled up and I went running. I hate the idea of running indoors (whether it's on a treadmill or indoor track), and if I have to buy a crazy amount of technical keep-you-warm gear, then that's what I will do, by Yoda!
