Why is my 5k time so crappy in comparison to my other PRs?

i'd guess your times up to 3200 are on the track. i suspect the others are not. there's one reason for a difference. secondly, it sounds like you don't run enough miles to do well at the longer distances. do longer runs and do some somewhat long runs at a good pace. that should solve the problem and make you faster overall, as well.

Your drop from 1600 to 3200 is pretty bad as well. As an undertrained freshman in HS I was about 5:00 and 11:02 in the 1600/3200. I probably had more speed than endurance. Try cracking 11:30, then 11:20 in the 3200. Then try carrying that extra speed to longer distances. Try to get where 6:00-6:10/mile pace feels fairly comfortable, and one that you can maintain for a 5K race.

Yea my PRs for the 5k, 3200, and mile are practically the same as yours. I haven't really raced the 10k before but i have a little more speed with a 2:11 800. But either way you look at it I suck. I also plan on hitting a 60 mile week this summer to make a run at varsity. this will be my last year and hopefully i'll run in the 17:00s for cross.

Thats a damn good PR for the 10k. It looks like you respond really well to mileage. Your PR for the 5k will definitely come down if you keep up the big miles this summer. Good luck.

tempo runs--4-7 miles, maybe 20 seconds off race pace, once a week.

are you really mark matusak??From old high school Loyola?? if so how long was you longest run, and what sort of running schedule did you have in high school, mileage, workouts, doubles, cross training??

Thank you guys for all of the input. So my 5k is about 6:20 per mile, so I should do one run per week at approximately 6:40-6:45 pace?

I am going to go for it this summer. This motivates me to do it now...
