married chiming in here. We've always done sports together.
I do see partnerships where one does, the other doesn't and there's more work involved in maintaining the relationship.... less time together, sometimes different fitness levels etc.
I agree that the bike dating is a good first filter.You are going to have to weed out the jerks and the dorks no matter what you do. Does your local cycle club do singles rides? I have heard of that, that to me sounds like fun.
