What is different about this year? Well, first of all, the weather has not been nearly so compliant. Right now there's still snow on the ground (had some flurries last night) and I've been happy when it gets all the way up to 40ºF.
On the WAY upside, I am in much better shape than I was at this time last year. My piriformis has not been bothering me at all and despite the excess of trainer workouts, my attitude is good. Here's to hoping the weather improves soon!
