Dr. Andy remarked in a comment that I should be running. I am. Sort of.
This week was scheduled as a last easy week before I start my real training. Because it's a low mileage week, I decided to push the pace a bit last night when I ran. I did a 10 minute warm-up and then did 5 minutes on, 5 off for the next 50 minutes. I wasn't going all that fast, but each repeat got faster, dropping eventually to a 7:00 pace.
By the time I went to bed last night, my glutes were screaming. I hadn't done squats for over a week and then did 3x15 yesterday morning to start my weight workout. I was only using 115# for the squats, but I worked on good form for all the reps. Add the faster running at the end of the day, and my legs were a bit tired.
Today, I'll do an easy hour of running before I teach skiing all weekend. Right now, I'm scheduled to teach skiing on Tuesday, but I think I might get out of that and start the new year with a 20 miler. I've only run longer than 12 once since Labor Day, so a long, slow run to start the year sounds like a good idea.
