Help improving 200m dash

[sprintingtiger]

I am a college sprinter and my primary race is the 100, I can run it in a time of 10.58 automatic but can only run the 200 in 21.9. I know I should be faster than this with that good of a 100 time. My problem is at about 150 meter, I tighten up extremely bad, and my legs run out of juice. I have no problem running the curve in the 200, I'm usually in the front of other low 21 second runners till about 130-150. I know I should be able to run a faster time, my body type is tall and lean, I am 6'2'' 185 pounds. Built like a 200-400 runner but run the 100 the best. Is there a certain type of training that would help me achieve a low 21 second 200, or different weight training. Thanks!

The key is fast relaxed running. Try sessions such as:
3 sets 3 x 150m @ 90% with 60 second recovery and 10 minute set break
or
2x (4x200m @80% of 200 PR with 2 minute recovery) 12 minute set recovery
or
3 sets 300m @ 95% of 300m race split time (60 second recovery; then do a 150m fast and relaxed in sub 1.
