Gov – Let's put it this way. My 200m speed puts me at about a 51/52 400m, but I'm only running 54's right now. I'm a 200/400 type. I know a 400/800 kid that goes about 23.5 in the 200m and 2:03 in the 800m and ran 49.51 at region. I know it's possible. My only thing is that I don't know which aspect I personally should go after considering my speed puts me close enough to 49. 400m, but my endurance is lacking. As of right now I plan on doing lots of enduance work next year and far less speed work than this year to try to close the gap and if all works out I'll be able to open up in Feb/March at about 52/51. If I do that, then I'll have to decide if speed training or more endurance training is the way to go.
It's so hard knowing so much….:(
