Solid Myerstown TT today. Very minor headwind on the way out. Minor tailwind on the way back. Not much flag movement. Mid- to low-80s.
Average speed: 19.75 mph
Distance: 36.71 miles
Cruising speed on the way out: 20.5 mph give or take
Cruising speed on the way back: 23 mph give or take
It's very likely I would've broken the 20 mph average speed threshold, but I had to stop at four different traffic signals. Rare. One of them was the usually empty Richland intersection on the way back. The slowing, stopping then starting up again really impacts the average speed calculations.
