The National record for elite men in a 40 k tandem time trial is 33.65mph For a mixed team 30.87 mph. http://www.usacycling.org/forms/records.pdf

Those are efforts by the fastest amateur cyclists in the country, with full TT setups (i.e. discs, areo bars, skin suits, booties, TT helmets) in a full TT effort for 1/2 to 1/4 of that distance.

I am certain, no one in the U.S. is averaging 30-32 mph for 100 mile regular rides, solo, much less doing it on a standard road tandem 25 years ago.
