Just to expand on this point slightly. I know the Nice finish to the Tour in 2024 was a GC day as it was a Time Trial, but what if it was the same circuit as there was in the women's TDF this year (i.e. laps of the Col d'Eze)? Would that have been an OK way to finish a Grand Tour?
I agree about the "de facto 20 day race" as a concept, but then that's where I say this should be written in the rules. The sport is by definition abitrary, so we can avoid the bad look of last minute changes by saying from the start "this is what the rules are"
Personally I'd have no real objection, as it's clear it's a GC day if they make them race Col d'Eze laps. I don't think it would be a good idea though, but I appear to be almost alone in thinking the parade + sprint is fine. I think you should ask the riders though, it's them that will decide - which is largely why the late changes occur.
I don't really have an issue either as it's not dis-similar to the current 5 km rule.
HOWEVER, it needs to be set out in the race rules before the event starts, and not a last minute decision.
They also should say that the first 20, 30, 40 or whatever kms of the final stage are neutralised too, for the photos and champagne sipping etc, and then the race is on properly.
I'm not all that bothered about late changes - they happen all the time for weather etc. and we're going to have to get used to them on that account as they'll be more frequent from here on in.
I also think it would be a shame if there were a very small gap - say a handful of seconds - in the podium placings and you
didn't let them race. If the race is actually so tight that getting away on a kicker on the final day is going to decide it, then let them have at it imo. I think we'd see the GC riders racing for bonus seconds on the Champs Elysée if the difference going into the stage was under 10". The point here is that if the only thing that would change the GC on the last day is
bad luck then I'm happy to neutralise it. If it's possible to win it by skill and strength then race it. The question is what stage have you designed and what are your expectations of who will race it and how it will be raced?
But again, run it past riders first, it's them that should have the final say
