Same But Different

I took my 12.8 mile ride and made a slight modification to it. I wanted to get a full hour of riding in so I extended my ride to 14.7 miles. I was quite impressed with myself not only did I increase my ride length but I increased my average miles per hour to 14.7 mph. I finished the course in approximately 1 hour. I'm trying to figure out when to push hard and when to ease up a bit. I know my limitations and I know my strengths; it's just a matter of understanding where to use them and what to do to recover from what I call leg burn out. I've noticed that if I pace myself my legs don't get as tired but my time is not nearly what it should be. It's just a matter of getting to know how to take it all. I'm trying short little bursts of energy with more cool downs in between to see where I fit in. It seems that if I consistently push my self the harder it is for me to maintain and the more time it takes to recover. I would be very curious to know how I ride on a road bike. I have determination.
