Anybody done this hiking trip?

My wife and I would like to do this in the summer of '25, but I don't think she's into hiking for 7-10 days straight. Maybe a 3-4 days. I figure we'd fly into Paris, take a train down to Chamonix, do some hiking, and then head out for other things.

I welcome any feedback or suggestions. I've been to Paris a couple of times, but never got out of the city. Would love to see Versailles, but that may be a different trip.

TIA

Following. This is relevant to my interests. I'd love to hike whole loop.

I did it 6 years ago Flew to Geneva shuttled to Chamonix stayed a night then started the next day, September 1, finished on the 12th. Even then which is late as we encountered 2 blizzards we still had to book our huts. Food was great and fun in the huts there are also villages to stop and eat along the way whether in France, Italy or Switzerland.
Never re ah on got cold as you are on the move. The race was going on then and really do not know how they do it. Lots of falls. From the racers.

Great trip and I would definitely do it again.

did this in 2022 at 65
spent 2 weeks with one rest day
the refugios are fun
all have bars which you need at the end of the day
food was amazing
started and ended in Chamonix
a one and done and had fun
if you are not into hiking then just spend time in the villages and maybe take the lifts up and do some day hikes
it is not for the casual hiker so make sure you have trained some
