One word, tandem. I am a reasonably fast rider who likes to pound hills, she doesn't. I like going no less than an hour, she wants no more than 20 minutes, if she is the one pedaling. Compromise is the tandem, I go as hard as I want, she sight sees, then, when I am 20 minutes from getting back, she kicks in to haul my collapsing carcass the rest of the way.
