I ran 3 on the treadmill in my basement this morning. I went back to an old trick to vary my training. I started out at 6.8 MPH and I bumped up the speed by 0.5 MPH every time a commercial came on. Then when the show came back on, I bumped it back down by 0.3 MPH.
Well I was watching ESPN Sportscenter and during my 3 miles there were only 2 commercial breaks, so it was a pretty leisurely run. Still it gives me 9 days in a row and 23.5 miles for the week, so it's a good start to my new year.
