Yesterday, November 28, I ran east along an open road that is very flat. Wind at my back was a steady 40-45 mph with gusts over 50. First time in my life I ever spun-out the top gear on my MTB. It's a 42x13 and I run road tires on it, no knobbies. GPS said I was maintaining 35-37 mph. Even at that speed I felt no wind on my face and no rush of air past my ears. What a weird sensation. Fastest downhill speed I've done on this bike before was only 33 mph and that for a hundred yards. I maintained 35 plus for 3 miles yesterday. Could not turn the pedals over fast enough. Anyone else go flying yesterday?
