I have been running for about a year now. my long runs ( 1/week) are usually between 6 - 7 miles. I run betwen 20 -25 miles per week as I am training for my first 10K (already ran a few 5k races). I want to increase my speed and endurance. According to most training programs you should run at an easy pace about 60 - 90 sec.s slower than your race pace.
My question is: If my goal is to increase my race pace speed, shouldn't I be increasing my training pace? several times during my runs recently I felt that I could have run faster, but I don't want to over-train. If I continue to run an easy pace, how will I ever increase my race pace? I include 440s and hills 1/week during my training already, but if I continue to train at 10 mpm, I don't see how my race pace will improve. Any advice or suggestions would be appreciated. for reference this is the program I am currently following. the 10k race is June 22.
