This is just a list of 100 great runs...not the hardest, but a great collection of runs ...many of them world classic.
I did a quick look, but I can say I've skied at maybe 25-28 of these runs. There are some names I didn't recognized and some that aren't on the ski map, so I wasn't really sure.
Regarding the 5 meter drop...not sure if he's talking about the waterfall or the fact that mayb the 1st 5-meter is sharp drop (which I would agree).
