Well, I didn't do any significant additional activity yesterday. I was pretty tired from the race, and my mother was visiting, so we enjoyed that.
In fact, I wanted to get to bed early last night, but did not, so I skipped my morning workout today. This is my recovery week, so I had planned to do some foam rolling, but I decided it would be better to get 45 minutes more sleep. I did have the opportunity to slip in about 8 minutes of foam rolling on my hamstrings and IT band. I'm still feeling pretty fatigued.
Before my half-marathon, I will definitely have to get more sleep!
