Hi everyone! Thanks for the welcome! I did day one on Friday going 3.8mph for walking and 4.8mph for running, I think I did okay. I started out with 4.0/5.0 but it was too hard and I didn't want to overdo it. I talked my fiance into doing it with me too, but he is much faster. I guess that's the advantage of treadmills, you can run with a companion who can go way faster than you.
Maria -- I thought c25k would be a slow-paced program since it is designed for people who are out of shape? If the distance increases are more than 10% maybe I will just add some in-between stuff . . . My knees are almost entirely better now, since I found the real secret to knee-health for myself: wear supportive sneakers all the time. If I wear sandals or heels or anything else for more than a day or so, my knees start to hurt. But as long as I wear my sneakers, everything's fine! Pretty weird. Luckily I can wear sneakers to work.
Allison - I'm using the time and distance displays on the treadmill instead of podcasts or stopwatch. I guess that's one advantage of running on a treadmill instead of outside! I didn't have any knee problems until I'd been running for about a year. I think after I made it to the three miles, I probably jumped up too fast to 4 miles, then 5 miles, plus speed training, then it was too much for me.
Onthetee -- I like to chat but at the gym I usually just plug in my iPod and blast the music.

In the past I found that I can go farther if I have music on loud, because I can't hear my own breathing! If I hear myself breathing hard than I'll think it's tougher than it is. Of course now I'm trying for a slower pace so I don't hurt my knees so that's kind of beside the point. I don't think I'll be ready for a 5k soon though, since I'll be increasing at a pretty slow pace (plus I'm going on a honeymoon for three weeks in October!).
After Friday's workout I did some leg strengthening and my legs are still a little sore! Plan is to do W1 D2 tonight, more leg strengthining tomorrow.
