X 2....that is a lot of miles in 2 days on a MB....even with slicks.

Honestly, that is a lot of miles in 2 days for most people, even on a road bike. If you don't want to purchase new bikes, train for the entire time on the MB, trainer ect and then rent roadies for the ride, that may be an option?
