Leif Whittaker is a seasoned mountaineer, coach, and storyteller with a passion for helping individuals reach their peak potential—both on and off the mountain. Growing up near Olympic National Park in Port Townsend, Washington, Leif developed an early love for the outdoors, inspired by his father, Jim Whittaker, the first American to summit Mount Everest.

At 15, Leif embarked on his first independent wilderness adventure, a 20-mile hike into the Olympic backcountry to climb Mount Olympus. This formative experience ignited a lifelong journey that has taken him across the globe to ascend iconic peaks, including Aconcagua, Mount Vinson, Denali, and Mount Everest—twice.

Leif served for 10 years as a climbing ranger for the US Forest Service on Mount Baker, where he was dedicated to preserving wilderness areas and ensuring the safety of visitors. He brings a diverse range of outdoor experience, including skiing, rock climbing, kayaking, sailing, and whitewater rafting.

After graduating with honors from Western Washington University, Leif pursued his passion for writing and storytelling. His writing has been featured in outdoor publications worldwide. He is the author of My Old Man and the Mountain (Mountaineers Books, 2016), an award winning memoir praised for its humor and honesty. He is also a sought-after motivational speaker, having inspired audiences from leading businesses, tech companies, nonprofits, and educational institutions.

Leif’s coaching philosophy is centered around empathy, positivity and communication. His approachable demeanor and consistent encouragement helps athletes build a strong foundation of physical and mental resilience. He specializes in preparing athletes for the challenges of high-altitude mountaineering and many other endurance pursuits. His coaching philosophy emphasizes:

Consistent communication, positive encouragement, and accountability.
Expert training guidance tailored to your specific needs, whether you’re tackling your first peak or summiting Everest.
Practical advice based on years of mountaineering and coaching experience.

Kind words from Leif's athletes

As a non-competitive ultrarunner and climber, I thought, ‘I don't need a coach.’ I was wrong. It took a life-or-death situation for me to figure it out. An especially bad case of Covid attacked my respiratory system and left me with acute respiratory distress. After 30 days in the ICU, I had lost over 40% of my lung capacity to scarring and neurological damage. I spent another 16 weeks in intensive rehab learning to walk again. It took me another 9 months to extend that to a mile, and then I plateaued. I spent 9 more months trying to build up to running an aerobic mile at any pace, but I just couldn't get there. I'd followed Scott Johnston since reading Training for the New Alpinism and reached out to him in desperation. Scott connected me to Leif. To say Leif steepened the recovery curve would be an understatement. Within 8 weeks, I ran my first aerobic mile since the hospital. 10 weeks after that I led a rock climb again and finished a 50K trail race. Leif has invested the time to get to know me physically and psychologically. He often pushes me when I want to ease up and enforces some recovery when I'm running on all cylinders and getting greedy for more. I think it's equal parts science and intuition, but both are backed with his investment in analyzing me and my performance data to make day-to-day individualized coaching decisions. For the first time in a long while, I'm dreaming big again—and that's priceless!

Climbing Mount Baker has been a dream of mine for years. And even though with most things I am confident I can work hard and achieve the goal, I put this off for many years because I was scared of what mountaineering would be like and I knew I'd have to be in great shape. Getting to work with Leif made me feel confident that I could do it. I knew I could trust in the plan he laid out to get me where I needed to be. I would not have managed these climbs (or even been confident enough to sign up for them) without Leif doing the advance planning and keeping me accountable. I hope he realizes what an impact he has in helping people achieve their wildest outdoor dreams!

I worked with Coach Leif Whittaker and Evoke Endurance in preparation for my 2025 climb of Mount Everest from the Tibetan North Side, and I can say with complete confidence that Leif’s coaching was the single biggest difference-maker on the mountain. Initially, I wasn’t sure if monthly 1:1 coaching was necessary—but looking back, the close-knit, highly personalized training was absolutely worth it. I’ve been on several expeditions in the Himalaya, Alaska Range, and Andes where I didn’t follow a formal training plan. Because of that, the contrast was undeniable: on Everest, my body performed at a different level—stronger, more durable, and more resilient than on previous climbs where I simply wasn’t in my best shape. I’ll be working with Leif and Evoke for all of my future expeditions. After experiencing firsthand the impact their coaching had on my Everest climb, there’s truly no substitute. I also appreciated Leif’s flexibility in adapting my workouts when I was traveling for photography work. Without his expertise, I would have been completely lost trying to train effectively on the road. We all invest so much time, sacrifice, and resources to pursue these objectives. It only makes sense to dedicate ourselves just as fully to the training that sets us up for success. I’m incredibly grateful for Leif and Evoke—my Everest experience wouldn’t have been what it was without them. I’m already looking forward to the next training plan!

I started working with Leif trying to prepare for Denali, coming from what we discovered was a pretty severe case of "aerobic deficiency." At first, spending hours hiking at what felt like an impossibly slow pace was hard to trust, but Leif never just handed me workouts—he explained the purpose behind everything we were doing. Understanding the "why" made it much easier to stay patient and commit to the process. Over the course of the year, I watched my aerobic fitness improve dramatically, worked through a few minor setbacks, and arrived at Denali feeling both physically and mentally prepared. The result was a successful summit, but more importantly, I never felt like I was hoping my training would be enough—I knew I had done the work. What I appreciated most about Leif's coaching was that he treated the process as more than just building fitness. He helped me understand training, pacing, recovery, nutrition, and the mindset needed for a long expedition. That confidence made a huge difference on the mountain. If you're looking for a coach who will not only make you stronger but also help you understand how to train for big mountain objectives, I couldn't recommend Leif more highly.
