Having never run a national, how many team usually show up to one? I just read at the RPM board that the 2.9 mile course will be used, so if you got time it will be worth the drive. I have raced with 62 teams on that course and it wasn't so bad. I am just trying to figure out how many people I will be passed by that day. (#of teams)(avg. 3 per team)= # of passers very scientific.
