Did 15 last night, and am supposed to do a timed 10 miler after work. That wind has steadily picked up through the day and is now over 21mph and gusting over 30. Should make for one huge suckfest of a TT tonight.
Edit: Holy suckfest. 14-15mph out, 30mph on the way back. Guess which direction we rode. Heart rate was 170+, cadence in the low 90's, 0% grade and I was still getting all of 15 mph into the wind. I can't believe I had to resort to the small chain ring on the way out.
