I've been following this running program that is really great. At least for me. I haven't seriously run in a really long time and was basically back at square one. I knew I had to start all over. But I also knew that it wouldn't be like when I first started when it took me 30 minutes to walk/run a mile. I was in slightly better shape then that but not much. So when trying to start back running I wanted to be careful that the program was challenging enough that I didn't get bored and it pushed me a bit. But also that it wasn't so hard I injured myself. I looked around and looked around and looked around. I considered couch to 5K but decided that was too easy for me. And too confusing, run for 200 yards, walk for 200 yards. It's a great program and it helped a lot when I started running, but it was not what I needed right now. So I continued looking. Most programs I found were either way too easy or too hard. So I kept looking. Then I found a program that sounded promising. About.com 3 weeks to a 30 minute running habit. I looked the program over and it sounded perfect. You start out 1 minute running/1 minute walking. After a few days it's up to 2 minutes running/1 minute walking. Today, day 8, we kicked it up to 3 minutes running/1 minute walking. I like the pace, it increases almost daily but then will take it back a notch to give you a rest. By the end of the 3 weeks you will be doing 5 minutes running/1 minute walking. That's a fine place to start a serious running program from. Also the have you running 3 or 4 days in a row. Now that is something I've never done because of my knee but guess what, it's okay. Anyway, I'm stoked about it. I feel good and I'm out there running again.
