distance perception, running
Aug. 5th, 2011 09:57 amI keep fiddling with heart rate and rest and speed and weather (I can't change that last bit, but I can plan around it) to find my optimal pacing for running longish distances. I had the thought of running from home to the Old North Church on Sunday. This trip takes about 45 minutes in a car. On Sundays, riding the bike to Arlington Heights, waiting for the bus, sitting on the bus for half an hour, and then taking the red line to the green line (my usual combined route) takes somewhere between 1.5 and 2.0 hours, depending on the waiting times between connections. My impression (I don't remember why) was that it's 18 miles. Google maps claims that a running route that includes the Minuteman Bike path to Arlington Center and then (choose one) veers onto Broadway, ultimately going via Charlestown, or goes down Somerville Ave and follows the Green Line tracks from Lechmere would be about 12 miles. Huh. That's a pretty big distance mis-match between measured & perceived. If I planned on a 12 minute/mile pace to allow for crossing lots of streets and getting water somewhere, I could do that in 2.5 hours, not wildly longer than the usual way of bike + T. Whether I'd feel like ringing a quarter peal after that is another question.
