What's the slowest mile that anyone has logged using the MAF system? I've been at this for almost 9 weeks. My MAF is 127 (age 43 minus 10 for blood pressure medicine), and I was just able to "run" my first complete miles without walking to stay under MAF. I have to say, I'm discouraged. Although I've been active my whole life (I ran a half marathon last year), I realized from the excellent FAQ's at the beginning of this thread that I was in serious need of this type of training, but I guess I didn't realize how bad I was aerobically. Well, this week has proved it, my aerobic system stinks. My first logged "runs" (I'm not sure both of my feet are ever off the ground at the same time) was nearly 20 minutes. I can certainly walk much faster than that. I'm definitely going to finish out the 12 weeks. I'm hoping to see at least a little more improvement. Sorry, I just had to vent a little. Happy Thanksgiving, everyone!
