With my upcoming bike tour, I've been logging all my training miles on the Surly.
My reasoning is two fold. First - I want to get accustomed to how this bike rides. The verdict so far - fabulous. It's not as fast or responsive as my Specialized, but it is a smooth, comfortable ride. Secondly - with this bike being relatively new, I want to break it in a bit so I can make any fine adjustments and assure there are no mechanical glitches. The verdict so far - flawless. She runs like a well oiled machine.
