If on an academic scholarship and you keep up with the good grades in college, assuming you aren't just plain awful, any coach is going to love having you as you would likely help boost the team's GPA which is a big deal within the athletic department. As mentioned above, send email/call via telephone which does work, tell coach you are on full ride academic scholarship, give HS mile and two mile times and would like to walk on and run with team. You cost the program nothing and if your good enough to make the team/travel (don't have to be top 7 for this usually), all the better. GL. We had several runners who walked on at our school. They never did make a team, but we took them with us when possible and became great friends. If your HS coach as any pull, ask him/her to help.
