035: How To Build Endurance and Run Faster For Longer

Key Points

• The core principle for improvement in running and life is endurance, defined as the wisdom to patiently and consistently endure the long-term process.
• To run faster for longer, foundational strategies include gradually increasing weekly running volume (not more than 10% per week) and applying the 80/20 rule (80% easy, low-heart-rate runs).
• Proper fueling and nutrition are critical, controllable factors for success, emphasizing high carbohydrate intake to replenish glycogen stores for energy during high-volume training.

Summary

The speaker begins by reflecting on a pivotal 2021 conversation with a man in Leadville, Colorado, who identified "endurance" as the secret to success, not just for a 100-mile race but as a universal principle for life, business, and relationships. Endurance is framed as an outcome achieved by those wise enough to patiently commit to and endure the long-term process.

The core of the discussion focuses on practical, foundational tips for running faster for longer distances. The first tip is to strategically increase running volume (weekly mileage or time on feet) by no more than 10% per week to mitigate injury risk and allow the body to adapt. This increased volume should primarily consist of easy, aerobic runs as per the 80/20 principle, where 80% of running is done at a low intensity. The speaker recommends using the Maffetone method (180 minus your age) to find your maximum aerobic heart rate and stay below it on easy runs to build a strong aerobic base, which ultimately leads to improved speed and stamina.

The second major tip revolves around fuel and nutrition, highlighted as a key controllable factor for performance. The speaker shares his personal nutrition strategy, which involves consistently high protein intake and, during high-volume training blocks, significantly increased carbohydrate consumption (500-600 grams daily) to ensure muscle and liver glycogen stores are full. This provides the necessary energy for long, intense workouts. He stresses that proper fueling is something athletes can directly manage to set the conditions for success, unlike external factors like weather or course conditions.

Throughout, the speaker uses his own running journey—from a challenging first marathon to training for a sub-2:45 marathon—to illustrate the compound benefits of consistency. He concludes that improvement in running, as in life, comes from enduring the process through patience, strategic volume increases, and dedicated attention to nutrition.
