I think the number finishing outside the time limit says a whole lot about the stages and their difficulty. It's simply overload, physically and mentally. This years Vuelta has the feel of an SAS selection course, harder, longer, higher, more, more, more. Only two rest days as well, they could actually have done with a 3rd. I think ASO need to re-think how the Vuelta is defined, especially at the end of a long season so close to the worlds.
