Sunday's double century will be at a light to moderate pace (average speed 18-20mph), since the speed of the group will be restricted to that of the slowest rider. The first half will be fairly hilly, and the terrain will become flat in the second half when we start across the plains of Northern Indiana.
can you define 'fairly hilly'? as Hocam said, the weight on the Surly LHT will only be a penalty on the climbs. Once you get into the flats, it's all about pacelining and there won't be much of a difference between the LHT and a regular road bike in that scenario. assuming a decent sized seat bag and good weather, you won't need the rack and fenders at all.
can you raise the handlebars on the Trek? flip your stem in reverse (assuming that it's already been 'flipped' for a more aero position) ? that might address your back issues and some of your butt issues. perhaps also move the Brooks to the Trek?
