Absolutely. A tandem has a definite advantage on the flats and downhill. Twin engine with little or no more "front" for wind resistance. In rolling hills the extra weight and downhill speed gives them a much further push up the next incline, too. The only place I could ever "best" my friends on their tandem was on a long incline.
My advice? Tuck in behind the tandem and draft.
