I don't like hybrid bikes. Unless you have a crappy MTB I don't see any difference other than lighter wheels and slightly different gearing on the bike you pictured. Personally I'd do a 150 mile on a MTB with a nice wheel set w/street tires and a *real* big ring. The flat bars will be problematic but the bike you pictured has them so that's a wash. Install some bar ends to give yourself some different hand positions, hell you can even use them as aero bars if you brace your forearms on them.
