The century ride is in two weeks.  Today I rode 80 miles on a mostly flat (as flat as you’re going to get in this part of Texas) course, and felt strong enough to continue when I was finished.  I continue to be surprised by my progress.  My improvement over the last 5 weeks of training is astounding.  5 weeks ago I rode 50 miles at an average speed of a little under 16 MPH, and was very tired afterwards.  Today I averaged over 18 MPH, and then finished mowing the lawn.  The training program works!
