Big ice skating day

I was on the ice for about 90 minutes today. There were only about 4 other people on the ice, perfect to practice circles on one foot, working on inside and outside edges. The most important thing is that I learned to relax the muscles in my feet a lot more and to put my weight further back which makes it easier to turn. I do have some sore muscles in my legs and decided to not go for a run today as well. I don't want to be too sore for my long run on Saturday.
I also found some stuff I wrote down from about a year ago. I recorded a run where I was running for 4 miles at 4.5mph but my heart rate was close to 160 at the end with the average heart rate around 148. That means that I have significantly improved since then.
I'm curious to see how my longer runs will go over the next couple of weeks.
