Climbing the 8000ers – the world’s 14 highest peaks, all located within the Himalaya and Karakoram mountain ranges – as a collective they represent the highest level of achievement possible in most climbers’ lifetimes.

We understand there are many opportunities out there to climb the most accessible of these peaks – but there is only one, to climb all (or any) of them, with an exped leader that holds the world speed record for climbing them all.

Why choose


Nims (leader on all expeditions) is a multi-world record breaking mountaineer, the fastest to summit all 14 8000m peaks. He has led 20 x 8000m expeditions with a 100% success rate, in both reaching the summit and more importantly bringing everyone home safely. Combining this with his UK Special Forces and Ghurkha heritage, he is the perfect bridge between Western and Nepalese cultures, providing an invaluable local Himalayan infrastructure and a totally unique skillset fine-tuned for success in the mountains. This is reinforced with a world class team of Sherpas hand-picked by himself through a process similar to the rigorous demands of special forces selection, all operating together with shared principles and code of conduct.

Safety through

If it’s controllable we control it, this is key to attain and maintain our industry leading strategy for success and safety. We maximise our options, agility and responsiveness by running totally self-sufficient expeditions, not relying on any other teams on the mountain to achieve our objectives. We are capable of setting up our own fixed lines (with a proven track record on all 8000m peaks) and have backups to cover all scenarios, from secondary oxygen supplies through to the ability and experience to operate our own rescue missions if the situation arises.
