For those speedy souls champing at the bit on those shorter distances, intervals have been proven to be the most important part of your week's workout -- whether your goal is getting fit or getting slim, as this article from the Mayo Clinic discusses. You don't have to time your intervals if you haven't the equipment. Jan & I alternated fast and, well, less fast between stop signs on our return trek. It was 3K well spent.

Sorry to say I will not walk this Saturday as parental duties call and I have to go the University of Waterloo open house.
