Walk to Run
I bought a Nike+ sensor about a month ago to go along with my iPhone 3GS. I intended to use it for walking my dog, but I came across the Walk to Run training program on the Nike+ site. I think I'll give it a try and see how it goes.
The first week is extremely easy. You just walk for 5 minutes, run for 1 minute, repeat, then walk for 5 minutes. 17 minutes total. I've been walking at 3.5 mph (stupid mph on the treadmill at work) and running at 4.7 mph. That's 5.6 kph and 7.56 kph respectively. I figure that's a nice and easy pace to start off. While I can easily keep up the walking pace for over an hour, I don't want to hurt myself with the running part.
I've been doing a bit of reading about running barefoot or with minimal footwear, so I am giving that a try. I'm not wearing my fancy running shoes with all of the cushioning because apparently that causes you to hit the pavement / treadmill heel first. Apparently, your foot is a good shock absorber but only if you hit the running surface with the middle part of your foot first. I can't imagine that it will be a dangerous experiment with the short distances I am running. If I get hurt, I'll stop.
I'm using Twiike to send my Nike+ run information to Twitter. The only thing that I don't like about it is that the workout is calculated as a run when most of it is actually walking. People must think that I run extremely slowly. 11:27/km pace? Heh.
