This week's guest is none other than record-breaking mountaineer and elite soldier Nirmal Purja MBE. With a humble upbringing in Nepal, Nimsdai had an early desire to become a Gurkha in the British Military. After achieving this, Nimsdai set his challenges higher, becoming the first ever Gurkha to serve in UK Special Forces (SBS) unit, which led to his interest in Mountaineering. Nimsdai now holds a coveted MBE title and 10 Guinness World Records – most notably for climbing the world's 14 highest summits in under 7 months, an achievement that defeated a previous world record of 8 years.

Now, Nimsdai is speaking with me about his bid for the K2 Winter ascent to claim one of the last remaining grand prizes in mountaineering, a feat regarded by so many, for so long, as impossible. In this inspiring episode, Nimsdai explains his motivation to complete the K2 summit in winter, his experience of writing his recent book 'Beyond Possible' and how his positive mindset has helped him achieve the impossible.
