We both find it more stressful but we also enjoy it too much to let that get in the way.
Bubba says he feels the pressure of being responsible for me, that whatever he does impacts me and, being the guy he is, would go the extra step to keep me safe.
We've only fallen once on the tandem. Came around a steep and blind corner on the uphill end of a bike path bridge onto a huge patch of sand where they'd removed the cement for repair. No signs, no warning, no nothing. Fortunately, we were going very slowly and he managed to keep the front end under enough control to step off and slow the tandem's fall onto its right side and I landed in the sand. I think the fall hurt him more emotionally than it hurt me physically. He carried some guilt for a while that he was at fault when I was thinking "thank goodness he did what he did."
For my stress level, I just had to learn to ride loose and relaxed, but that doesn't mean we don't do a lot of communication. Since Bubba outweighs me by 75-80 lbs (and 10" taller) every little movement he makes causes a reaction in the back. If he stops pedaling for just a second, the reverse force on my pedals can eject me off the seat. We don't put in a lot of miles on the tandem, but I think the size difference probably made us realize very quickly that communication was extra important.
To make it work for us, Bill talks a lot (which he's does anyway
) and I learned to let go of control issues, relax and go with the flow. I have to trust that he's doing the right thing and make sure I don't let my body react to every little thing. Basically, he talks a lot and I "ride stupid." Works great.
