Assuming you can pack light and compact:

Salsa casseroll
Soma smoothie ES (need to build it up)
Specialized tricross comp triple
Surly crosscheck or maybe pacer

If you go a mass-market road bike, make sure the gearing, riding position, toe and heel clearances, carrying capacity and ruggedness of the frame are adequate for you. If you're going fast I guess you'll be on 28mm tyres, maybe 25 or 32. Make sure your rear wheel is strong.
