Podcast Summary: Zach & Ian Sharman on "The Art of Ultrarunning" Guest & Book Intro: Ian Sharman (ultrarunner, coach, author) joins Zach to discuss his new book Art of Ultrarunning. The conversation draws from Ian’s decades of experience, coaching insights, and real race stories (including Zach in his world-record 100-miler negative split). Hiking vs. Running – A Key Lever: - Power hiking is a trainable skill that saves energy, improves durability, and allows better fueling, especially on hills or late in races. - Early-race example from JFK 50 (2012): Ian hiked a steep section while others ran; he was just as fast and fresher later. - Rule of thumb: If effort feels unsustainable, switch to power hiking preventatively before you redline. - Coaches should teach athletes to hike more than they intuitively want, especially in training to make it race-automatic. Pacing & Execution > Raw Fitness: - Core theme: “It’s how fast your slowest mile is, not your fastest.” Execution matters more as distance grows. - Ideal pacing is usually near-even or slightly negative; big positive splits (going out too fast) cost far more time later. - Real-world examples: Leadville wins (Ian never led at halfway but won by hours), Western States terrain favors negative splits for elites, flat 100-milers allow objective pacing data. - Mental triggers: Use interval-session logic, small “breaks” (hikes) early let you tolerate higher sustainable volume later. - Race-day psychology: Stick to your plan; ignore the pack. Confidence comes from knowing you’ll still be strong at the end. Durability vs. Running Efficiency: - Ultrarunning rewards durability and specificity more than pure running economy (e.g., sub-2-hour marathoners like Sebastian Sawe would need major compromises to excel at Cocodona or UTMB). - Variables that set ultrarunning apart: hiking strength, technical-terrain tolerance, heat management, and mental durability required for 100 mile mountain races. - Specificity wins: Practice what the race demands (hiking, backpack, technical trails, eating on the move). Muscular Endurance Training (Weighted Vests, etc.): - Ian has used weighted-vest uphill hiking for years, but only as a small, sustainable portion of training (often active recovery, ~20 lb vest). - Purpose: Build hiking-specific strength, leg durability, and volume without excessive pounding. - Not one-size-fits-all: Use it when mountains aren’t accessible; elites like Tom Evans/Ruth Croft do harder versions because they have extreme fitness and time. - Key principle: Target your weakest link (whatever slows you down most in past races). High-Level Mental & Tactical Skills: - Confidence, Discipline, Patience: Hold back early; think 10–20 hours ahead. - Adaptability & Flow: Race by feel, make micro-adjustments, stay in the “groove” where miles fly by effortlessly. - Learn from every race: Identify your three slowest miles and fix the patterns that caused them. Longevity & Individualization: - Training must evolve with age and life demands (Zach, now 40, still high-volume but more strategic with recovery, bike cross-training, and shorter intense blocks). - “Earn the right” to high-intensity or extreme sessions, don’t copy elite plans without the base. - Book’s philosophy: Same core principles apply to everyone, but execution is highly individual (flat-city runners, mountain dwellers, different ages, etc.). Ian’s Current Outlook: - Still racing marathons (downhill fast ones for fun) and planning more Comrades (aiming for 10 finishes and the green number). - Prefers single-day ultras and multi-stage races (e.g., Marathon des Sables) over 200-milers right now, loves the social/off-grid aspect. - Emphasis on enjoyment and long-term relationship with the sport over chasing marginal gains that could burn you out.
