20.1 MPH was my average on the way home last night...I had a light tailwind helping me but it was still a struggle. My fastest time ever is 50 minutes...and I was at 51 minutes last night. I usually roll right around an hour for my 17.3 miles...to get up over 20mph for an average I have to constantly remind myself to go faster and that gets harder to do as the week goes on.
