EDIT: Per the Randonneurs USA web site... Randonneuring is long-distance unsupported endurance cycling. This style of riding is non-competitive in nature, and self-sufficiency is paramount.

This thread pertains to single-stage ultradistance races, not randonneuring. Yes, there is some overlap in the sense that both are long-distance formats. Other than that they are pretty different animals.
