I only ran 3 miles today even though I had planned to be a bit more ambitious. I work nights and sleep days. Frequently my phone rings and wakes me up after only a couple hours of sleep. When that happens, I never get a good day's sleep. That happened today so I ended up getting up later than usual. But I gave myself a push and at least made it down to the treadmill to do a short run. I always feel so much better after a run, no matter how tired I may have thought I was.
Like I always say during my marathons - it's not as painful as chemo!
