As this situation (competing unattached) is mine exactly, (I am not on a college team, but hope to be) I bothered to go to the NCAA website and look up the rules. Here are some I think that apply:
17.7.8.1 Noncollegiate, Amateur Competition
17.7.8.1.1 During Academic Year
A student-athlete in the sport of cross country who participates during the academic year as a member of any outside cross country team in any noncollegiate, amateur competition (e.g., team invitational meet, exhibition meets or other activity) except while representing the institution in intercollegiate cross country competition shall be ineligible for intercollegiate cross country competition for the remainder of the year and for the next academic year (see Bylaw 14.7.3 for exceptions and waivers). (Revised: 1/10/91 effective 8/1/91, 1/16/93)
Associated Enforcement Cases Major Cases: 0
and then here:

this is more specific to the idea at hand. But it still does not bring to the point, what does not count as an "open" competition. If the meet is scored, is it automtically considered to disqualify. Many places run open/pro/unattached athletes in the same races as the intercollegiate athletes. The teams could still be scored, but does this count? The situtation makes sense in dual meet or conference meet, but what about in invitationals, they declare a team champion, but anyone can enter; just pay the entrance fee.
This is the definition that is given.
"In order for a competition to be considered an "open" event, the competition must be open to noncollegiate competitors and must be organized, publicized and operated as an event that is open to individuals other than collegiate competitors."
So what would qualify it to be as such. Would just the word "invitational" in the title count? To me that means that everyone is invited (as people have come and run pretty slow at invitationals) to compete. What would qualify as such. Would the meet have to run seperate races?
Just wondering on that last point. But in the situation listed, I (as a person reading rules), see nothing wrong, unless they travelled down there with the team, etc.
