My colleague and I are cheap...er, frugal and we park in the free lot at work, which is of course one of the futhest away from our building. She was curious to see how far of a walk it was so she brought her Garmin to work one day and discovered that we walk 1/2 mile EACH WAY to get to our office. That is 1 mile of walking each day! We were both pretty proud of ourselves.
Since the weather has been really nice here in Wisco, we have also been getting out around lunch to do a 1.75 mile loop around campus. It is amazing how much more energy you have after getting outside for a little bit halfway through the day!
