The key to a quick break in is this, your ass has to be in the saddle! I rode to work three hours early so I could get riding in before work, rode for four hours after work, skipped lunch and went riding, got up at 5 am Sat and Sun, rode all day. Do it by the book with lots of stops for cooling along the way, it will pay off greatly. I'm very lucky to have miles of nearly deserted back roads to run, and I took advantage of them. The trip to Minnesota will be great, I envy you!
oh, i wouldn't be so sure r80rt. i'm looking at 1200 miles of superslab over three days on what will likely be an open bike. i'll need to condition myself appropriately. but i'm young, so i should be fine by the end. it'll definitely be fun. i'll just have to make sure to bring a tent big enough for 2
I think I'd avoid the superslab if you can, that kind of miles on a interstate is brutal. I did 3700 miles in six days a couple of years ago, and did 80% of that on two lane roads. if you chose carefully you can cover some ground without all the truck traffic, and enjoy it more.
