In reply to Romain87s:
It’s a great route to aspire to. I’ve been aspiring to it for years... You need the right experience, partner, acclimatisation, conditions and weather. For the last three years, it’s been the conditions and the weather which have been frustrating me and my partners. Set off to do it in September 2015 but bailed from the top of the Noire (descending the super chossy normal route) because we figured the weather wasn’t good enough to carry on (which was the right call). The Noire South Ridge is a good route in its own right by the way, apart from the chossfest descent! Didn’t have the weather window for it when I was in the Alps last year and this year.
You need three blue sky days to do the route and you’d want the fourth day to be ok as well (it’s not a route you’d want to be getting on with an impending storm on day 4, partly because there’s a chance it will take you longer than 3 days and partly because storms can blow in earlier than forecast). You also don’t want to do it straight after a spell of bad weather as the rock sections need to be clear from snow (although one hot, sunny day may be enough for the Noire). Not the best idea to do it after a really hot spell either as I’ve heard of people getting hit by rockfall on some of the chossy sections in very hot, dry conditions. Unfortunately I t’s surprisingly difficult to get that kind of stable weather and decent conditions pattern in Cham, unless you’re there for the whole season and ready to go when the planets align.
If you are already an experienced rock and ice climber but don’t have much alpine experience, realistically you would need to plan for a long trip (at least a month, more likely an entire season) to have enough time to build up to a major route like that.
You need to be able to climb quickly up to HVS at altitude and with a heavy pack (so realistically you need to be solid at E1) and move together quickly and efficiently over moderate ground (as well as some pretty chossy ground!). You also need experience of doing long, committing routes and bivvying on route. So you’d want to do a few big TDs first to build up all this experience, plus some 4,000ers for the acclimatisation.
If you’re already reasonably fit, a good trad rock climber and comfortable in crampons on moderate mixed ground, the main training you will need is doing increasingly longer and more committing Alpine routes. Doing long Scottish winter routes will also be good experience, both for the mixed climbing and the suffering. Unless you have a lot of spare time, it may well take you several years to get that level of experience (that’s been the case for most alpinists I know) but the journey to get there will be fun.
I would recommend filling out your profile with your climbing experience - you’re much more likely to get interest that way for a serious project like that.
Good luck.
