Between casual and hardcore. I have averaged 4000-5000 miles a year the past 5-6 years. In the summer, when I have more daylight, I ride 5-6 times a week. In the fall, winter, and early spring I ride only on the weekends and run 3 days a week before work. My average speed will vary, about 15 mph for a club ride and 16.5 to 18 mph for a solo ride. That definitely puts me in the casual range.
But I love to ride!
