GT Options
I like a lot of the ideas posted here. Here's my take:
I know there's speculation about how reorganizing the three Grand Tours will wreak havoc on the other races of the season, but I think there is something to be said about riders who are built for grand tours, and we should cater to those guys because it's cool as hell. I would definitely want to keep the GT races 21 days - I get some sort of sick twisted joy watching those guys maintain form into the last week.
Ultimately however I think, along with many others, that the real path to success for GT races is to get all of the aspiring GC riders to participate in all Grand Tours. I like the Tinkoff idea of offering an end of year GT classification/award, but maybe in a less greasy way.
I see two options to promote universal participation:
01 - Flip-flop - Move the Vuelta to start the last week of April, and the Giro to start the first week of September. That makes better sense to me in regards to the time-of-year and geography and also adds a week between all three races. Is that enough recovery time to entice a hattrick? I have no idea.
02 - Is pretty much what Bavarianrider said: Kill the Vuelta as a Grand Tour and shift the Giro and Tour up a week or two, add a week or two between them. I like watching the Vuelta, and it's a nice net for riders who crashed out in spring, but ultimately, it's a mixed bag of talent. Somebody else already wrote, and I agree, nobody targets it. Why have it? Then the GC guys can focus on doing the double in top form - YES!
I hadn't given it much thought until today, but I like option 02 the best. It might also give an added boost in attendance and popularity to some of the shorter 1 week races.
Anyway, I'm glad there is so much speculation about the flip-flop/shuffle from fans, because this kind of "what's gonna happen?!" stuff gets me all fired up!
