When I'm running around sunny places like this:
there are a few things I must have before I hit the road (or sand). These include Burt's Bees lip balm, my iPhone, which I use for music as well as for mapmyrun.com since I get lost easily, sunblock on my face, and of course, sunglasses. Some people I run with think it's weird I run with shades on, but I feel way more comfortable for some reason.
Do any of you run with sunglasses on? Or is there something else you must have to feel comfortable to run for hours?
