Lately I have been doing 20-22 miles at a time on a Specialized Sirrus Comp. I avg. 13 to 15 mph on these trips over varying courses. I feel good but somewhat tired after these rides. I want to do a 60 miler later this month or early next. Now I am getting concerned that this would really exhaust me.
Did 22 miles yesterday in 91minutes. headwinds on the way back, rolling hills. Since January I have put 300+ on the bike outdoors, and many sessions on the stationary bike at the gym.
I am 59+ and really have no idea whether this kind of performance is good or bad. Not looking to break any records but would like to be recording an acceptable pace and would like to complete the 60 miler without falling over at the end. Any comments, suggestions??
