I called Sunday's attempt at starting C25K Week 1 Day 0 because I could only get through 6 jog minutes. I went back at it today, and had no problem at all. In fact, I feel pretty great just from that half-hour.
I think I identified some of my problems in the first attempt:
a) I smoked until Sunday
b) The ground was soft and wet and I had to look at my feet
c) I had to turn every 300 feet or so
d) I was into a strong headwind halfway through
While driving home today I realized the end of my street is flat and has a perfect sidewalk. I used the car and Google maps and determined that I had a 0.2 flat smooth paved loop with very little foot or car traffic. It was almost pleasant to run that route, and I got to see some neighbors I had never seen before.
I have a lot more confidence now that I have a safe extremely convenient venue that I too will be logging multiple miles by mid-May. Good luck to all.
