Email the coaches (head coach, distance coach and XC coach if they are not one and the same) at all the schools you applied to again, tell them if you are admitted or are still awaiting a decision and ask them what they do to fill their roster. Some D1s have try-outs, some take walk-ons, some have try-outs for only invited walk- ons, etc. The point is that until you hear directly from the coach, we are all speculating as to what they may be looking for. Only the coaches will know what the status is at their school for the upcoming year and your times are close enough to have the discussion.
Give them your stats, and be direct and tell them you are only interested in going to a school that allows you to continue in xc/track, and ask if you will have a chance to be on the team at their school. You are not asking for money and it is a fair question. Keep asking until they give you an answer.
