The last day of my four month, 6,000 mile, fully-loaded, cross country+ tour was a large (thousands of people) 75 mile, supported charity ride. Despite their being luggage transport, I rode my bike with all my gear. I dropped countless people and even had people drafting me.

Having toured with people and encountered many other people while out touring alone, I would bet my left front pannier that, on average, most of the self-contained touring population is fitter than the much of the general riding public.
