The Duffel Shuffle Podcast

David Goettler has been a professional alpinist for nearly 3 decades, and part of The North Face athlete team his entire career. With a focus on classical alpine style climbing on the highest peaks of the world, David has set out on a quest to climb in the way that suits him. 
For David, climbing the tallest peaks of the world is a dream, and the challenge is in their height. Climbing without supplemental oxygen and Sherpa support above basecamp is the only way for him to truly test his abilities. 
- David has successfully summited seven 8,000m peaks without supplemental oxygen, many of which required multiple attempts. On his fifth attempt of Nanga Parbat in Pakistan in 2025, David summited via the Schell Route and descended by Paraglider from 7,700m on the mountain. 
- David has gone on expeditions with countless partners, and the list includes some of the most notable alpinists in the last 3 decades. For David, finding the right partners for his objectives is almost as calculated as the climb itself. 
- While David believes that all professional alpinists should be climbing without supplemental oxygen and sherpa support, he recognizes that for non-professionals, just being in the mountains is what's important, and style should be chosen based on what each individual is seeking.

Still technically only a "few" weeks late, Sam and Adrian look back on 2025 and forward to 2026. This episode was delayed due to the Seven Summits series, but as we move into the new year, there's lots to talk about, from personal experiences in 2025 and goals for 2026 to the industry as a whole. 

- Adrian had a big year, with his 10th summit of Everest and the acquisition of Alpenglow Expeditions by Milky Way Park. Meanwhile, Sam started and finished his year on separate ski trips to Japan, but the highlight of the year was his growing family. 

- From expected films to impacts of tariffs, 2026 is sure to bring lots of interesting twists and turns. Andrzej Bargiel and Jim Morrison both broke the ceiling of 8,000m peak ski mountaineering, and expected films are potentially coming in 2026. On the other end of the industry, the ski industry may continue to see the direct effects of tariffs and other economic impacts. 

As we look forward to 2026, we want to thank our listeners for their continued support and encourage you to share feedback. Comment or message us what you like and what you don't like. Guest and topic ideas are always welcome!

Sam and Adrian wrap up the Seven Summits Series with none other than Mt. Everest. At 29,032' above sea level, Mt Everest is much taller than any of the other seven summits, and its history, notoriety and reputation speaks for itself.

While Everest has been well covered on the Duffel Shuffle Podcast, Sam and Adrian endeavor to provide an unbiased look at climbing the mountain, and compare the two regular climbing routes for guided climbers, with as little opinion as possible.

- Different "requirements" for prior experience exist on either side of the mountain, and many operators have their own prerequisites, but in general experience up to 7,000m is important. In theory, this experience and more can be gathered through climbing the other six of the seven summits.

- There are pros and cons to each side of the mountain, but the most important thing when considering an Everest Expedition is understanding what your getting from your operator. Budget and Guiding do not go hand in hand.

- While there are differences between sides in weather, infrastructure, rescue, technicality, access, etc. the each have reasonable pros and cons.

The sixth in our series on the Seven Summits, Carstensz Pyramid, is the tallest peak within Oceania. While some Seven Summits lists include Mount Kosciuszko in Australia, most modern lists acknowledge Carstensz Pyramid due to its higher altitude and increased technical challenge. Locally known as Puncak Jaya, the peak sits at 4,884m or 16,024 feet above sea level, on the island of New Guinea.

Unlike all other peaks on the list of seven summits, Carstensz Pyramid is a true rock climb, where climbers ascend a limestone ridgeline with both vertical walls and exposed traverses.

- Much of the climb has been fixed with ropes, including a span that now has a cable bridge, to accommodate the number of climbers looking to climb the mountain and prevent issues of overcrowding.

- Due to its relatively low altitude, as compared to its counterparts, climbing Carstensz is generally quite quick, and much of the true adventure lies in the many-day trek through the jungle to reach the base of the peak.

- Unfortunately, with a long history of unrest in the jungle, it has become standard to heli into basecamp for your climb. With ethnic tribal conflicts and civil disturbances, it's no longer feasible to trek through the jungle.

On Episode 45 of the Duffel Shuffle Podcast, Sam and Adrian head to the bottom of the world to discuss the Vinson Massif. This is the fifth episode in the series covering each of the Seven Summits, and while Vinson lacks some of the culture of previous mountains discussed, it makes up for that in the uniqueness of the adventure.

First climbed in 1966, Vinson is known by Seven Summit climbers as "The Last Great Challenge" as it was the final peak climbed by the first to complete the seven tallest summits on each continent. While not particularly challenging, Vinson is notable for its logistical complexity as well as extreme temperatures.

- Due to its relatively low altitude of 4,892m (16,050'), Vinson expeditions can theoretically be completed in a matter of days. That said, most expeditions last 2-3 weeks to allow for the logistics to fall into place, which can be severely delayed by weather and other factors.

- All Vinson logistics are managed by Antarctic Logistics and Expeditions (ALE), whose strict risk management practices have led to an incredibly high safety and success rate.

- A Vinson expedition requires a high level of mountain independence, primarily to manage the challenges of cold. As such, it's a great peak to follow Everest or Denali, and can also be easily combined with climbing Aconcagua.
