Treadmill

I run on the treadmill under three different circumstances. First is winter, when it may be unsafe to run outside (though that's a rare phenomenon); second is summer, when the air gets so thick I can't breathe and am soaked through just checking the mail; and third is when I have a particular paced interval-style workout and it's easier to head to the gym than to the track. My biggest worry in treadmill running is grossing out the other gym patrons with my habit of extreme sweating. Yesterday, with reasons two and three both in play, I ran 4 x 1 mile watching an old John Wayne movie without any sound.
