I do have a buff somewhere, but I think the wife hid it. She really doesn't like them. I suppose a peak would be handy for keeping out the sun and I'll probably slap on enough factor 500+ on my neck, but having fair hair means I sunburn easily.
I do all of my running either first thing in the morning or last thing in the evening. I've got an AL race coming up in a few weeks that starts at 11am. EEK!
