Absolutely. In fact I'd like him to captain so he'll be able to borrow the tandem to use with his two sons. This would be could training for moi, the better able to appreciate the stoker's plight.

Interestingly enough I had him on the back once a few years ago as he was transitioning from tri's. His pedal stroke was so smooth I couldn't tell whether he was in phase or out. Of course he had ridden a hard 90 miles the day before so he whined a bit. In any event downhills will be either a)special or b)terrifying depending upon one's perspective as we would total out around 390 lbs.
