Knowing about the 3 miles route is working out very well. Today I was minimally enthused about running because I knew that I had the option of running just 3 miles if I did not feel like 4. The good things is, by the time I get to the turn-around point, I feel pretty good, and I know I am almost halfway done anyway, so I go ahead and run 4 miles. Nice little trick. my time was about about 32 minutes. I haven't felt like I was running an 8mm pace, but apparently I was. we'll see what happens when I go longer on Friday.
