Why now? A physiological perspective on the first official sub-2-hour marathon

Area of Science:

• Sports Science
• Human Physiology
• Performance Analysis

Background:

• The first official sub-2-hour marathon presents a novel case for analyzing elite marathon performance determinants.
• Previous focus has been on theoretical physiological limits, shifting now to practical expression of capacity under fatigue.

Purpose of the Study:

• To re-examine the factors contributing to elite marathon performance, specifically the sub-2-hour barrier.
• To analyze the role of physiological capacity preservation and expression under late-race fatigue.
• To interpret the sub-2-hour marathon as an integrated athlete-technology-performance system outcome.

Main Methods:

• Analysis of split data from the first official sub-2-hour marathon performance.
• Examination of collective performance patterns within the leading group.
• Perspective-based interpretation of contributing factors, including physiological, technological, and environmental elements.

Main Results:

• The sub-2-hour performance involved late-race acceleration, not just pace maintenance, with a fast second half.
• The achievement was influenced by a collective performance environment rather than an isolated effort.
• Key factors include fatigue resistance, race execution, high-rate carbohydrate delivery, and advanced footwear technology.

Conclusions:

• The post-sub-2-hour era requires studying fatigue resistance and race execution, focusing on preserving physiological capacity.
• Factors like carbohydrate intake, footwear, and pacing strategies interact to support late-race performance.
• The sub-2-hour marathon is an extraordinary human feat resulting from an integrated athlete-technology-performance system.
