My first choice is always to run with friends. It’s amazing how time flies when in deep conversation. However, especially with a crazy summer schedule, that’s not really an option. On a very rare occasion (usually when my iPod is dead) I’ll run with no ear buds in. This sometimes leads to profound thoughts, but usually just makes me think about how I wish I was listening to something, how heavy my breathing sounds, and how much further I have to go.
