I ran four miles this morning in Boston, where it's pretty humid today. This run was my second run here and I figured it would be a more typical run in terms of traffic, and other runners--I ran on Sunday which is already a different sort of day plus it was a holiday weekend.
What I noticed the most today (aside from the flatness of the run) was that I was the only person running without some sort of MP3 player. I don't understand running with music--I want to hear the traffic so I don't get squished, and I tend to always run in tempo to any music I hear, and that would really bug me.
I wish I understood the allure of running with music.
