I rode 15 miles yesterday with a 10-15mph head wind with a average speed of 13mph, with 2 large bridges, and 6 miles of wet trails with hills and other random off road stuff. My average heart rate was 150 and my max was 188. i am 6'3 and 350lbs at age 21 is that good? bad? My resting heart rate yesterday here at work was around 45. My recovery last night was pretty good also i was kinda impressed!
