I did 7 miles today. It was very slow with a lot of walking, but still 7 miles. I kept telling myself that all the walking was what I needed to train my heart. It felt great. I just wish I could find an expert to talk to about my heart rate. I had a physical recently and am in excellent health. I am not worried at all, but want to be sure I am training properly. I am pretty sure that I'll do the 15k in February, maybe even a half in the spring.
You know after a good, long run, you want to sign up for a bunch of races.....lol.
