Depends on how hilly it is. Generally I can go further and faster on a geared bike once I'm out in the countryside and don't have so many lights etc to contend with, but on the flat the fixed wheel works fine for longish distances. I'll happily cycle 30-odd miles on one of my photography expeditions around London in the summer and barely notice it. Haven't tried to do a randonnee on the fixed yet though.
