Going to Glacier NP (1200 miles) this Aug/Sept. Need to get there fast. I'm planning to ditch my Surly LHT, racks and panniers, and take my Specialized Roubaix with Revelate bags. Taking the gas tank, jerry can, seat post and tangle bag. Should be at least 20 lbs. lighter. Considering using a "bounce box" to ship cold weather gear to myself ahead of hitting critical spots. And doing the hotel thing. Hopefully, this will result in century plus days.
