I found my super power - I can make headwinds double in strength merely by upshifting!
Coach decided my TSB was positive enough to cut the last day of recovery, so today's ride was 2:41 at the high end of endurance pace, IF was .79. I felt pretty damned good on the bike.
Wind was 15 mph at the start and 19 at the finish. At one point I was doing 28 mph in still air, at another I was at threshold in the drops on flat ground doing 14 mph. Hey, it builds character!
