66 yo (67 in October) @ 145 pounds and 5'7" tall. My preferred type of riding is endurance and distance but I like to mix speed into the rides as well. I ride between 30 and 44 miles/day often doing 60-66 mile rides on the weekend. I don't dwell too much on average speed because the daily ride route I do forces me to drop into speeds as low as 12 mph for a few miles. However, on the loop, I can keep a 18-21 mph average speed when I want to. I also belong to a cycling team and we average 10-12 charity rides a year, mostly 100K and century rides. Last charity ride was this years MS 150 in April.
