I've rode 33 miles so far. Three 11 miles loops with restful breaks inbetween. The first two loops were very relaxed. The last time around I hit it hard at the halfway point and kept the speed up to over 13 mph for the last 5.5 miles. There at one point I was going 25.5 mph.
Thanks, 20 mph tailwind. You're OK.
I'll probably ride the loop a couple more times today. I'll let you know....and I'll try not to nag.
