Thats what I think should be discussed here.We have a lot of experience, informations, we have a extensive topic we can talk about. Most of those people here are very (imo) informated and educated, so lets have a nice discussion about (a positive

) problem.
IMHO Its one of the best situations that can happen in cycling. Its a positive feature that someone attempts a Double. It would be even more gracious for cycling if those 4 riders would do it.I think it would be a pretty huge subject for international media who often dont care a **** about cycling.
As for the analysis. For now, I only gonna write my opnions training/schedule wise. (time is precious)
First I would start with the end of a season. I think AC already made the first step torwards to be in the best possible condition to win a Giro - Tour double, and thats DNS in Beijing. The base of success for him is to have a proper monthly rest. Then to start slowly training during november, december and build a proper base.That means ride couple of thousands km during off season.Not too hard because imo there shouldnt be any 'early spring' peak or something like this.
He should reach his first peak form in 1st-2nd week of Giro. Why in 2nd? Obviously cuz he needs to make a gap to the opponents into the 3rd week and be ready to slightly decling by the end of the race in my theory.With Sestriere going as recover pace as possible to win in GC e.g. by a minute.
That means he shouldnt do ANY classics.I would prefer Algarve - Cataluna -Romandy.With algarve completely off form and contesting only in Romandy.
The question is, what to do after Giro? Hard to say, Im not sure what is the best option.I would suggest he should rest a LOT and then ride Route du Sud (suisse and dauphine too hard). I think rider who contest a Tour ftw after giro shouldnt have more than 35-40 days of racing.
And then the real deal will come.The Tour 1st week. IMO in this scenario he would be in a bad condition so a key is to not lose time in 1st week.Then ride probably full gas, cuz considering a Vuelta there shouldnt be any big rivals, and of course because he will need to go 110% at Tour in order to win it.
