Suggestion from a older, (married 39 years) disparate rider team. I do two rides. I first go out, either by myself or with a select group of friends, and do a hard ride. When I get home, we go out and enjoy an additional tandem ride together. I am generally pretty fried, so the additional "cheap miles" doesn't sound like a training ride to my wife. We can go at a little slower pace. If we ride hills, I really feel it because I have already had a hard ride. I end up getting stronger. I use it as recovery. She enjoys being with me and I love being with her.
