Team composition: typically 7 runners per team for NCAA D1 championship; first 5 finishers score; Substitutes (#6 and #7): "displacers" — affect opposing team scores but don't add to own score; Officials: meet referee, course officials at marked points, finish judges, recorder, timing crew
Why people argue about this
People often assume that all 7 runners get a score just for participating, which leads to arguments about why one runner might be dropped early if they're not performing well. The confusion arises because NCAA D1 cross country rules specifically state only the top 5 scorers count towards their team's total, regardless of how many runners they start with.
