Did a Century on a Mongoose Crossway 'Comfort Fit Geometry' hybrid. When I told my LBS about my feat, the reaction was 'huh!' Then I explained that it took all day, sunup to sundown,10 1/2 hours, including about two hours total breaks. Then the reaction was 'oh, ok'.
The "Comfort Fit Geometry" is, in my estimation, real comfort. The frame's top tube and seatstays make a curved arch from head tube to the dropouts, and the bottom tube is curved similarly. Over 5600 miles on the bike, and just recently broke its first spoke, non driveside rear. Presently I'm riding it on dirt (two track) roads in local forests, after changing tires from 32mm to 40mm. This model was discontinued in 2005 (when I bought it for $150).
