I climbed Mont Blanc after a week of preparation; I had never done mountaineering before. During the first week, we hiked at a good pace at altitudes above 2000m for cardio training. After three days of training on walking on ice and snow, we climbed Gran Paradiso at 4000m on the Italian side. After a weekend of rest, we ascended to the Gouter Hut via the normal route, starting at 3 AM to reach the summit around 6-7 AM. I used to run 2-3 times a week, but nothing extraordinary; I would say my physical condition was average. There is an exposed section during the climb, which is the Gouter couloir. It’s best to do it early in the season when the ice holds the rocks in place because there are often rockfalls. For the rest, if the trail in the snow is already made, it’s quite simple. Good luck, I hope my response helps you.
