At my course there is a Championship Tournament, a Senior Tournament, a Ladies Tournament and a Junior Tournament.

If you are a male, 59 years old, you may only play in the Championship Tournament. A male or female 60 or over can compete for the Championship. Everyone plays from the same tees.

Senior Tournaments exclude everyone under 60.

So tell the old fuddy duds they are welcome to your tournament as long as they can hit it from the same tees everyone else uses. Otherwise, tell them to form their own tournament.
