i would love to help. im only 23 but have been running since i was 7 and have studied the sport the entire time. ive raced everything from 100m-half marathon. ive trained for speed and endurance. ive tried running over 100mpw and 21miles on training runs. i ran at FSU under Bob Braman and ran at Arkansas after that. if youre new to this FSU is ranked #1 in the country this year and ARK has won 42 national titles! i work at a running store and coach a youth track team. this is my life and i am willing to help anyone i can. email me and ill get back to you indepth.
as far as books/tapes go…doug brown isnt the best when it comes to coaching. great athletes dont always make great coaches. thats why he isnt a track coach anymore. but a good name for mondo to throw around. he believes in under-under, under, distance, over, and over-over distance. confusing i know. but thats a bad form of Seb Coe's multi-pace training. Peter Coe (sebs dad and coach) has a great, but very very technical book out. "better training for distance runners" if memory serves me.
so the best book in my opinion for the basics of training is by jack daniels, "the daniels running formula". i believe hes a bit weak on the speed side of things but overall good for distances. and he has charts that take the guess work out of training paces .
i think you have things off to a great start, but needs a few changes and maybe a broader knowledge of exercise phys and seasonal training progressions.
