I apologize for making another one of these threads but I really would like to know if I have the ability to break 5 at this moment in time. I’m a HS senior running about 50 mpw. I ran 18:38 during XC at the very beginning of the season but failed to PR at any other meet. I have a very good aerobic base but my speed has always lagged behind the others. My best 400 ever is 1:07 and my best 800 is somewhere in the 2:20s. Today, we did 6x400 in 1:12 each with a 400m jogging rest followed by 6x200 in 34-35 with 200m jogging rest. Do you guys think I can break 5? Also, I ran 3 miles this morning (workout was this afternoon), 9 easy miles yesterday, and 8 easy miles on Monday. Thanks!
