Is there any (purported) scientific basis behind this idea? Does it really make a difference having a big tour in your legs 49 weeks before the TdF (i.e., the previous year's TdF) or 42 weeks before (Vuelta)? Just curious.
I think the benefit comes from the fact that a rider has a high level of fitness prior to their off season, meaning they don't need to do as much conditioning work before they can start doing high quality race type training efforts.
