Thanks for the wealth of info already.
amonkie - I've not taken any planned rest days. Last week we had a very busy day and ended up skipping my walk. A week before that I was having a number of days that I felt under the weather with nausea and sinus congestion. I didn't do the walks for 2 days then. Otherwise I've not taken days off.
I moved into the 1 1/2 miles by starting out and walking briskly until I felt loose enough to run. I would break into a run, run until my legs started to feel the strain, push just a little further, then slow to a fast walk again. I did that several times throughout the whole 3 mile walk. Eventually I moved into running from about 1/4 of the way unto my walk and then walking the last 1/4 of the distance.
I have done hardly any stretching at the end though I try not to just come home and plop down on my butt. 10 minutes of stretching might definately help. I will try that.
Slims- I read about the toe raises in another website and you've confirmed it. I believe that could be some help.
I will also have to try different shoes or subtracting the orthotics. I have been wearing K-Swiss but I have some reeboks. I have not worn the reeboks though because it seems like they aggravated my heal. About 5 years ago I broke a chip off the inside of my left heal. That's what my orthotics have helped with, I'm not landing ON that chip and causing it to irritate.
Also I hadn't thought of using the Aleve BEFORE I ran. I like that idea. Prevent some of the inflamation at least maybe.
Ratbastid - I like the idea of landing mid-foot. I've tried to run fairly levelly as I tore some ligaments in my right ankle about 6 months ago and I'm anxious about doing it again. I will have to look into that Chi Running thing. It sounds great. It's encouraging to hear that you're not the only one not running miles and miles every day. I've seen several people on my walks every day and I see them running the entire route. It makes me feel like a wimp when a much older man passes me up regularly. lol
Spiritsoar - The more advice the better. Let me have it!
