Sub 27:30 8k?

Your easy days are too fast relative to the speeds/volume you are doing your workouts. If you were doing 7x1600 @ 5:25 average on 1:30 rest I could see "easy" being around 6:40 pace. But since you are doing 3x1600 with what must be close to 3 minutes rest with the 800m jog then you are probably putting to much effort in to your easy days and not enough on your hard days. Or be conservative and add a little more volume on your hard days at the same pace and then run your easy days closer to 7 minute pace.

If you are running sub 30 for 5 miles at your steady state pace then you should already be south of 28 minute shape for 8k.

I'm not a coach this is just like my opinion, man.

Currently in very similar shape. Last night I ran 16:36 in a 5K. Three weeks ago, I ran 27:29 for an 8K.

Generally, I'd say you're not doing enough miles and they're not quite quick enough, though you're not far off.

You don't need to be sub-7 every run. A couple of your easy days should be an easier pace relative to what you're doing in workouts. For example, you are running about 50 miles/week. 8 miles on Tuesday at a pace that is only 1:13 slower than you want to race for 8K is faster than it should be for an "easy" run. Slow down on easy days and you'll be able to speed up on hard days and you'll get sub 27:30 no problem.

you're definitely at high risk to overtrain before you start your college season and the real workouts start. I'm guessing that your steady state runs and intervals are harder than they should be at this pre-season point of the year. You should take at least one very easy week before the season and more easy days in between such work. Relax, there will be plenty of opportunities to run fast workouts during in-season training and racing. If you slow down now and come in well rested you should have no trouble breaking 27.

Good points by many. Yes, you can go under 27:30 but XC sometimes depends on the course so assuming it is a fair course, you should be able to do it. Your "easy" runs are too fast. I would recommend a longer easy run but at a slower pace - 7:15 - 7:30 - keep up the good work

You are in great shape to have a good race or two to start the season and be toast by the end of September. Run more, slow down, and drop the interval workouts and "hard tempos" which sound a lot like time trials.

Looks like you're on the right path. Your workouts during the season will take care of getting you to your goal. I would make one more general suggestion - slow down your "easy" days. Looking back on my college career (I got to 3:51 for 1500 and 24:41 at Franklin Park in Boston), I wish I would have ran slower on easy days. Proper recovery will help you over the lifetime of your career.

I vote yes. As long as your're not overdoing mileage totals (i think college freshmen should top out at 70-75 per week) I think you're good.

Yes, easy days easy. 7:30 pace isn't too slow for your recovery days (at least 2 a week).

Longer runs longer. 1:30 to 2:00 every week at an easy (7:30s or so) to moderate (low 7s).

Tempo run only about once a week or so, at 6:00 or so.

I just recently time trialed 8k in 28:55 on a moderate XC course in trainers. felt very easy. This was maybe 75-80% effort
