OP: Seriously? Why in the world would you *ever* tell someone during an interview that you quit a previous job to go on a long bike ride? [/QUOTE]

Presumably because there's a significant gap in the chronology of his resume. For any job that involves sem-skilled labor on upwards, you're going to get asked why you left previous jobs. If there's a time gap of at least a couple of months between jobs, employers will want to know why. That's standard operating procedure.
