Last week I walked more regularly than I have since High School:
02/02/12 0.5 miles
02/01/12 0.25 miles
01/31/12 0.5 miles
01/30/12 0.5 miles
01/29/12 0.37 miles
01/29/12 1 miles
And I was just slightly sore and tired.
I don't have something worthy of going into my DailyMile log every day, but I'm making a lot of little changes, like standing up in meetings, or while working in the lab, doing squats while I have a minute of downtime waiting for something, getting more housework done. These little changes are nearly impossible to measure, so it's hard to say how much I've improved of late, but it's moving in the right direction. As the weather warms this spring, and we start to get evening sun back, I need to make a regular habit of walking the puppy after work and really see more measurable improvement.
I've given up on Mind the Ducks this spring. I've not done enough work this winter, not really increased my maximum mileage at all, although I've improved my ability to recover after a walk and repeat again the next day.
