100 miles is 160 km. Tour du Mont Blanc is a 170 km trail around Mont Blanc and surrounding mountains, crossing from France to Italy and then Switzerland before returning to France.
Ultra-marathon runners can do it in 20-45 hours. They carry little but gel packs/etc.
My brother and I hiked it a few years ago, carrying a tent, cooking gear, food, etc. It's a lot of up and down and even if the down doesn't exhaust you, it grinds your knees. Elevation gain is 9,600m (so 31,000 feet). We did it in 9 days, from memory. Could've done it more quickly or walked longer each day but we generally allowed time to select a secretive but flat camping spot (camping wild on the Italian side is somewhat illegal), cook, wash clothes in the river, etc.
The up hill bits definitely slow you down.
Afterwards, we said "Never again!" but I haven't stop thinking about it since and would go back for sure. Highly recommended. Stunning scenery and a great challenge.
