My rides with my wife are typically at a slower pace than I would ride if by myself. And some times that is the point. It's nice to just cruise along, enjoying the ride. Stop for lunch, or at some shops, etc.. It makes for an enjoyable, relaxing day. We do have one rule, we each go up hills at our own pace, I wait at the top(even though she tells me I don't have to, I know better). If I want to go and ride my legs off, she'll ride her own ride.
