You've got some great advice on here for the most part. I read all of it.
*Read all you can on Arthur Lydiard on the internet while realizing that
he was often misquoted. It is also true that everyone is different and a good coach knows how to adjust workouts.
XXX. Avoid over training by doing too many tempo, hard intervals, or races!
Some posters on here suggested running some or all of your training runs fast! That is a recipe for disaster. The rule of thumb is to be able to talk at a conversation pace for most of your runs. Your pace will get faster over time.
+ Do one speed development workout per week. Some sprint coaches do not know what this means! Arthur Lydiard had his athletes do this all year.
Speed is the most difficult thing to build in an athlete, so it is important to be consistent. 2:04 marathoner Ryan Hall used to do at least one speed development workout per week. He was coached by his father in high school.
What is a speed development workout?
This is where you do runs of 80 meters or less at varying degrees of the VO2 MAX (Your top speed) As with anything you have to start slowly.
Perhaps the first day would look like this:
Slow mile jog, dynamic running drills, 6 x 50 meter strides
4 X 80 meters @ 80%, 85%, 90%, and 95% of VO2 Max.
4 x 50 meter strides, mile jog. Static Stretching.
Follow this with a recover day run of 2-6 miles very easy.
Later you can (SLOWLY and GRADUALLY) add more sprints, or
short hills, rope jumping, Fast Dynamic Running Drills, Plyometrics, and
etc. You have to take this seriously and progress slowly with the number of repetitions and intensities!!!
But you do need a coach to watch you. Talk to him/her and tell them
what you think you need. Communicate how you feel about your progress. You are already a good runner or you would not be running. It is crucial that you feel good about yourself!
I've been in the sport for 46 years as a runner, coach, and writer. However there is a lot to learn, and even more to learn about life. You cannot separate the two!
