I did my first post-GDR ride yesterday. I did a really short 40.83 miles in 2 hours, 45 minutes (incredibly slow, recovery pace at 14.91 mph).
It was really weird getting back on a road bike after doing almost 400 miles on a mountain bike covered in gear. My sense of balance on a bike was totally destroyed. I sat down on the bike and pedaled out the driveway onto Moody St. and the bike felt flaccid beneath me. I literally just about fell over. It took about 5 miles to start going in a straight line. By the end of the ride, it felt natural. Almost needless to say, I rode clear of busy roads.
