And on that note, let's see how they'll do in 2028.IMO the real problem with the current GT spread is that they've moved them further and further forward. Vuelta was a September race, Giro was anywhere between mid-May and early June until not very long ago, and the Tour has also started to creep into June. Makes the weather a lot more problematic for both Giro and Vuelta. IMO Giro should start in the 3rd weekend of May, Tour the weekend before Bastille Day, and Vuelta first or second weekend of September. Of course, that doesn't really work in an Olympic year, but the trend exists outside those years too + shouldn't impact the Vuelta.
Olympics run from july 14th to 30th, so either TdF starts super early or it runs in august.
