Today is Thursday. The 4th day of the week (the work week, that is). I have gone to the sports center here on campus 3 times this week, walking 1 mile each time. My knees are killing me. But I’m feeling good. I actually got up to a speed of 3.3 mph this morning, the fastest I’ve walked since my mom walked me to school on the first day of first grade, at which time I had to run to keep up with her (my mom, in case you didn’t know, was an Olympic speed walker in another life and has yet to realize that it wasn’t in THIS life…needless to say she is a FAST walker). But this is not about my mom, it is about me. My legs are burning right now. I’m supposing this is a good thing.
