Thanks Meg for the detailed explanation. I started laughing when I read your post because for me 5.0 - 5.5 mph is a RUN. I think I need to push myself more. Tuesday my husband did intervals, but I just ran at my usual distance at my usual slow pace. I'm going to do some intervals on next Tuesday. Now, I'm trying to decide if I want to do them on the treadmill or on the indoor track. I think the treadmill will help me control my speed a little better. In regards to running a marathon, it really helps if you train with someone and since your father wants you to do it with him, you already have a training partner! Also, check out some running clubs in your area. I trained for the marathon with my husband, but I wished we trained with a running association. If we run the marathon this year, then we are going to sign up with CARA (chicago area running association). Also, I find it easier to run outside along a trail than on a treadmill or even on the streets.
Okay, my running stats for today:
3.98 miles (37 laps) in 45 minutes and 46 seconds.
