I walked to Dairy Rd. yesterday and today -- there's too much going on at work and I'm too tired to take on more. Today's round-trip time was 21'37", a little faster I think than yesterday, but I didn't keep time. I focused on pushing with the thighs again on these walks. I believe it yields better times, but it's more work.
My esitmate of the Diary Rd distance is 0.7 miles (per Google Maps). Assume that has an error term of plus-or-minus .05 miles. Then the round trip is 1.4 plus-or-minus .1 miles. Today's time computes to a 16.6-minute or a 14.4-minute mile, depending on which way the error lies.
