Eliud Kipchoge’s extraordinary feat of running a marathon in under two hours was not only a triumph of human endurance but also a testament to the power of teamwork and strategic planning.

As Kipchoge ran with a rotating group of pacers, new research utilizing wind tunnel tests with action-figure manikins sheds light on the role these pacers played in achieving this remarkable achievement, the study was conducted by mechanical engineer Massimo Marro of the École Centrale de Lyon in France and colleagues.

Kipchoge’s historic sub-two-hour marathon was a carefully orchestrated event, with pacers taking on a critical role. These pacers, comprised of other skilled runners, adopted a strategy known as drafting, effectively shielding Kipchoge from air resistance by creating a slipstream, reducing the drag force.

This technique, often used in cycling and racing, can significantly reduce the energy required to maintain a certain pace, allowing the lead runner to conserve vital energy over the course of a long race. The ‘V’ formation can be seen in birds that fly a long distance during their migration as it reduces over half the drag.

Recent wind tunnel experiments, featuring action-figure manikins in the role of the marathon runners, both Kipchoge and the pacers, provide fascinating insights into the impact of drafting on Kipchoge’s performance.

The tests indicate that the pacers played a pivotal role in shaving off an impressive 3 minutes and 33 seconds from his finishing time. This critical time reduction propelled Kipchoge below the iconic two-hour barrier, culminating in a record-breaking time of 1 hour, 59 minutes, and 40 seconds.

The findings of that marathon, presented in the Proceedings of the Royal Society, underscore the intricate dynamics of running at elite levels and the significance of teamwork and strategy. Kipchoge’s accomplishment was not solely an individual endeavor but a collaborative effort, with each pacer strategically positioned to minimize air resistance and enhance his performance.

Beyond its implications for marathon running, this research sheds light on the importance of aerodynamics in various athletic disciplines. Understanding how air resistance influences performance can lead to innovative training strategies and gear designs that optimize efficiency and speed.

While some purists about the marathon argue that Kipchoge’s marathon accomplishment was augmented by the drafting technique, others contend that the collaborative nature of the endeavor adds an exciting dimension to the sport. The sub-two-hour marathon was not just a display of physical prowess but a demonstration of meticulous planning, teamwork, and the relentless pursuit of breaking boundaries.

As the world of sports continues to evolve, propelled by advancements in technology and scientific understanding, Kipchoge’s feat remains a symbol of human potential and the boundless possibilities of pushing the limits of human achievement. The combination of individual dedication, strategic collaboration, and innovative research has paved the way for a new era in athletic excellence.

Eliud Kipchoge’s historic sub-two-hour marathon is not only a testament to his physical abilities but also to the intricate science behind his achievement. Wind tunnel experiments featuring action-figure manikins highlight the pivotal role of drafting pacers in reducing air resistance and propelling Kipchoge to his record-breaking accomplishment.

This research underscores the synergy between individual effort, teamwork, and scientific innovation in the pursuit of athletic greatness. Kipchoge’s achievement stands as an inspiration to athletes and researchers alike, demonstrating the remarkable outcomes that can emerge from the convergence of human dedication and scientific understanding.

This upcoming September, Kipchoge and his fellow competitors will undertake a groundbreaking challenge: a professional marathon in Berlin aimed at breaking the elusive two-hour marathon barrier. Notably, it was in Berlin in 2022 that Kipchoge established the existing official record of 2 hours, 1 minute, and 9 seconds.
