Also, riding at sea level makes a big difference. I live and commute at 3000 ft above sea level and often ride in the Canadian Rockies at 3500 - 4000 ft. I was vacationing in Ontario this summer at 300 ft above sea level and my average speed over 50 miles increased by 2 mph. I definaly felt much less fatigued riding at sea level.
