Interesting, I've read a bit of your log on CF and when you had one on Elitetrack. Your old log on ET is basically the reason I write one there now.
Is the mileage that you do run more of the high quality tempo rather than just slogging out a lot of useless miles?
I was thinking about building to 50 easy miles a week pretty quickly(3-4 weeks) then incorporating a lot of the auxiliary work while dropping mileage to about 30. Then adding in some tempo runs and increasing the pace of the general mileage.
I'm a 400/800 guy with PRs of 51.4 and 2:00, I have never done any more than about 25 miles a week, does this set up look good for me?
No, no. That set up does not look good, there are no quick fixes, I would not recomend you double your volume quickly, all that will do is injure you. If anything I would just start with adding good warm ups as well as maybe a medball circuit and core to what you are currently doing.
