8 points needed for a letter
4 pt - beat prior year's XC pr at early season 5k time trial or a time standard:
Fr - 20:00 (3 pt)
So - 19:30
Jr -19:00
Sr - 18:30
2 pt - finish top 5 for team in an invitational
1 pt - finish 6 or 7th for team in an invitational
1 pt - beat at least half the 5th men from other teams in an invitational if you're not in our top 7
4 pt - finish top 5 for team at conference championship
2 pt - finish 6th or 7th for team at conference championship
1 pt - beat at least half the 5th men from other teams at conference championship if you're not in our top 7
Represent team at District, Regional, or State Championships = automatic letter.
In 20+ years of coaching, I've gone through several iterations of standards. At the end of the season, this tends to yield letters in a manner that "feels" right to me. I've given a "coach's choice" varsity letter one time, to a kid with disabilities that worked their tail off during the season for 4 years.
I've never felt a need to give a letter to a 4-year participant. I think if they really wanted a letter they could work hard enough to earn it with the time trial and points for beating other teams' 5th men. The thing I am most likely to tweak would be the points for the time trial - I would reduce the number of points for just coming into the season in shape.
Note that I do aggregate times for meets that have JV/Open and varsity times so that the 5th man is the 5th fastest man for each team on that day regardless of which race they ran.
It seems kind of harsh, but I don't have exceptions for injuries that curtail a season as I don't have a method of doing that fairly.
It's far from perfect, but as I said it has tended to yield results that feel about right to me and encourages coming to season in shape and performing well at the end of the season.
Years ago I had a time standard for meets as well. That was a complete disaster for a multitude of reasons - a short-lived experiment early in my career. One short course and afterwards you've got lots of varsity runners without a need to run well when it counts. It means kids hate slow courses (hills, mud, etc - all the stuff that makes for a great race).
I complete agree that on really deep teams there needs to be some objective way of earning a letter other than being top 7 at the end of the season.
