This morning I got out for a 6.38 mi. TT run. I try to do this TT a couple times a month to measure my progress. Last year I did a PB of 17.7 mph. This year my goal was 18 mph. Last month I hit 18.1 mph on my first attempt. Today, despite a 3 mph headwind in one of the fast spots, I did 18.4 mph. Hot and humid. I was dripping sweat when I finished.
