Okay, so Tandem isn't always the perfect solution. I find that i also like to ride a single bike. So here's what I do: I don't always ride with DH. Sometimes I let him ride with his gang ... other times we ride together with the understanding that he's going to stay near me. This way, he gets to spread his wings and get some good hard training, and yet, we still can ride together.

and sometimes we ride the tandem... we try to get the best of both worlds.
