Hi Alex, I’m also London based and have about a year’s worth of climbing behind me, up to Scottish grade IV, WI3+ in the alps and just did a winter ascent of the Cosmiques arete. Very much still building in terms of knowledge, experience and fitness but I can say that i’m trying to be the best alpinist I can be, given where I live. Happily meet up for a chat/climb sometime as it’s always handy to know of other climbers with Alpine aspirations beyond the climbing wall..
