Despite the risk of such "side-effects", long-distance bicycle tours are something I wish I could do. I've all but drooled over the Epic Tours described by Adventure Cycling. The catch is that these tours are very expensive for me.
And, would my hybrid bike be suitable for such a tour? Is it sturdy enough? Can it take racks (for panniers) on the front wheel? If I want to do a tour that has a lot of climbing, are the gears low enough? I'd need to buy or borrow a good bit of equipment if I took a self-supported tour: sleeping bag, tarp or tent, and so on.
I would also need a LOT of training. Those Epic Tours last several weeks and cover several thousand miles. That's a far cry from the occasional century, not to mention that my current daily rides of 14-15 miles don't come near to the day-to-day demands of an Epic Tour.
On the other hand ... I remember seeing a poster way back when I was in college. It showed a kitten peeking out over the rim of a wastebasket that had a tiger's face printed on its side. The caption read: "When You Dream, Dream Big!"
