I partially agree with what you say. I find it much easier to make the miles while on a trip. There is no excuse "Oh well, I'm home". When home isn't in a fixed location getting in the miles each day is much, much easier. I can ride consistent high miles away from home much easier than I can around home. If I can't find routes around where I live that gives me the miles than I can come up with too many excuses to stop once I get home and not do any extra riding for the day.

The simple problem is the training does help make the travelling much easier. The key secret to keeping the training going to make a challenge for yourself. Set a crazy, unthinkable goal and shoot for it. I ran into a simple problem last month of giving up on my plans to be heading south for a winter long bike trip down south this winter. I knew I had to get everything ready to spend the winter up here in New Hampshire. I don't have a car so I knew I needed to get the house ready, food and miscellaneous items that I needed to buy. As a result I started making numerous trips to the grocery store and other places to get ready for winter. By the time I had all the catch work done I was pretty much riding 60+ miles a day. I had started nice long stretch of at 40 miles a day and decided to see how long I could carry it on. My summer had been such trash for biking this year...compared to last year, that I felt like a horrible slouch. I even had a nice stretch of back to back 100+km days going. I decided to keep up the stretch. Today makes my 30th consecutive day I've ridden at least 62.3 miles. Stumble into crazy challenge and let them take you over and that will help to keep the monotony of training from taking over.
