Assuming (always a big assumption) that this is not a troll:
1) There's a *lot* of the spring semester left. Get serious about your classes *right now* and you can demonstrate how you "made a competitive response to a tough situation so I could achieve my academic ambitions" yadda. Same for the first semester of your senior year. Show in your college application essays how you've overcome your brief slump--"met the challenge" yadda.
2) You "can run 9:14." Does that mean you *have* run it, or that your workouts indicate it? If, as a junior (and before any significant outdoor action), you've *already* run 9:14...then you should already be hearing from tons of schools (including some Ivies).
3) With your current academics, a 9:14 as a junior (and no felonies, say), and a reasonably good ACT/SAT, you should be accepted for admission at the flagship campus of nearly every state university in the country. No worries, really. Now whether you'd be accepted for the *team* is a separate question, but having the academics for admission should be no problem.
4) To maximize your opportunities and choices, take the SAT and/or ACT seriously and *prep* for it/them. There are a bunch of good prep books: Kaplan (full disclosure: I used to teach/edit for them) and others do a good job. Get off the Internet or the TV every night half an hour earlier than you're used to, and do some test prep. Good test scores (and your improved grades) could very well entitle you to some *academic* scholarship aid. This can be important to you because so few boys get more than partial *athletic* scholarships nowadays, and the academic $$$ can be key.
5) If you show improvement (getting back toward your usual standard) in your spring/fall grades, and get a solid (doesn't have to be phenomenal) ACT or SAT score--which I think you can do, given your success in the APs--then thinking Ivy is actually not far-fetched. A school/team like Cornell, say, could be a good match. No athletic scholarships in the Ivies, but their need-based aid is fantastic: as long as your family isn't truly wealthy, you'll get to attend college for little or no expense.
Anyway, good luck. Keep us posted on developments, please. And a final tip: don't spend more than an hour a week on LRC. Use the time you save to study for your courses! All best--
