Hey, I'm getting faster

My rest pace during my first mile and last mile was about 11:30. In fact I averaged that pace during the whole run (my recovery runs were slower but my fartleks were faster). That is the pace I was running at last fall before the cold weather set in. During the winter, my rest pace was 12:15 - 12:30. I don't think my speed training had much to do with my increase in pace since I've only been doing fartleks for three Saturdays. My guess is that it is probably the increase in temperature that we've had the past few days. Regardless, it's nice to be going a little faster but still running a comfortable rest pace.
