8.5 miles one way. Mostly down hill to work. I get the better workout on the way home, when it's normally warmer. Leave home, freshly showered and soaped, but sometimes it was the evening before. I keep a box of hand sanitizer wipes at work. Wipe armpits and crotch if I get there sweaty. Usually not needed. Even summer mornings here tend to be relatively cool and humidity is low. I do change clothes and underwear when I get to work.
