quite different. but least you can say you did a century even if it was just flat.
For the purpose of a ride being a "century", it doesn't matter whether its flat or hills or mountains. As far the OP's question, 100=100=100, like the previous poster said. It doesn't matter if it is organized or ad-hoc or solo.
