In this episode of the Uphill Athlete Podcast, Scott Johnston talks with elite alpinist David Goettler on a gamut of topics including David’s training history; approaching the big mountain ranges fast and light; the importance of base fitness; learning from failure; fitness versus pre-acclimatization; approaches for a pre-acclimatization “training camp” leading up to high altitude expeditions; the advantages and disadvantages of hypoxic tents for acclimatization training; David’s experience of attempting Everest without oxygen and the challenges of climbing in this style on such a popular mountain; training for marathons as a mountain athlete; and training in less than ideal situations such as a global pandemic.
