I commute 5 miles one way and I no longer "Race my bike" but instead "Ride my bike". On my commute to work I am showered that morning and take my ride slow even while sipping on coffee. Even on hot days I can make it to work with maybe a little sweat on my forehead, but not my entire body. I wear light, hi-wicking clothing on my commute then change into my uniform when I get there.
After work, I change back into my riding clothes and head home. I have to shower after work anyway so I get get as sweaty as I want
