I ran 58 in the 400 and ran 2:18 in the 800 but i didn't run it that often.
a sample week during the season was this:
m
4x800 at 3:20
t
8x100 (sometimes on a slight downhill) at 400
w
5x300 at :55-60
t
6x200 at 36,36,33,33,30,30
F
4x150 accelerators
S
race
What would be a good summer training program? 800 meters is the longest I ran at one time during the season besides our 3 lap warm up.
