Glad you're getting some preparation for the hills in NC, Emily. That would be a shock, coming from a totally flat place.
NY, I was going to tell you to skip today's ride, but I didn't want you to lose your motivation. You did what your body needed. And by the way, it's natural daylight that regulates the SAD thing, not really sunlight vs. cloudiness. People in warm, sunny climates still get it, because of the shorter hours of daylight. They have a lesser rate of it, because they probably spend more time outside, but moving to a place like FL, CA, or AZ does mean you won't have it. I remember when I moved to Florida, when winter came and we were on Standard Time, I felt like it was summer and they chopped half the day off, when it was getting dark at 4:30 in December! It took a year to get used to that.
I went to spin yesterday, tabata today, and spent 4 hours moving and unpacking stuff. I will probably go for a short ride (15 miles) tomorrow. I am going to commute Tuesday (in the 60s) and Wednesday go on my group ride if it's a close start (I have a haircut at 3) or just do a long ride myself. It is supposed to be 70 on Wednesday.
