Not all treadmills are created equal

I had to do another treadmill run the other day. I've come to realize that not all treadmills are created equal. The ones at the Y are fairly new while the last two I've used were much older. The older ones have a better feel to them (with the exception of the buttons that only work if you really press on them). I think it has to do with the fact that the older treadmills have lost a lot of their cushioning and hence they feel more like the road. Regardless, I ran indoors this past Saturday and took the opportunity to really push myself. I managed to do a couple of miles in the 8-minute range and even sprinted up to a 7-minute pace and then back down. It was a good run, for a treadmill. I won't be able to get outside until at least Thursday. And, of course, the forecast is for 20's by then.
