Only a handful of mountaineers have climbed all 24 of New Zealand's 3000m plus peaks. Kiwi mountaineer Alastair McDowell and partner Hamish Fleming are the only ones to have done it in under a month and in a single push. It's a feat that usually takes a lifetime. Alastair will be speaking at the Mountain Film Festival in Wanaka, Queenstown and online running between June 24 and July 2.
