Today I had an errand to run at the bank downtown. Normally I "don't have time" to walk downtown from campus, but when I realized that if I drove downtown, I "wouldn't have time" to do my exercise walk, I figured I would combine the errand and the exercise.
Google Maps says the distance is 1.1 miles one-way. What it doesn't say (but I later confirmed with a topo map) is that the elevation change is about 220 feet. In the event, I took 19 minutes outbound (downhill), and about 21 minuts inbound (uphill) -- not bad, considering that I needed a breather at the middle and again at the top of the stairs (!) next to the engineering labs.
I admit to being a little exertion-giddy for a few minutes after, and I worked up a little too much sweat to be comfortable. And I bought myself a very nice cup of Thomas Hammer coffee downtown to sweeten the sweatin'.
