How long do you think a league should run?

I prefer when they’re at least a quarter. Depends on frequency of meet-ups and if there are special or escalation rules. But for the most part, I prefer them to be the life of a set.

Either a quarter, or a month. Although a month might be a little to short.

We ran ours for 6 weeks, I think 6-8 weeks.

3 miles

I think 6 to 8 weeks would be somewhat fair. I think 4 weeks is way to short. I'm really not a fan of the strength of schedule is fair to people and can be to easily abused to insure that the top 4 are fixed.
