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!
