The INEOS 1:59 Challenge was an ambitious and historic event in the world of long-distance running. It aimed to push the boundaries of human performance by attempting to break the two-hour barrier for the marathon distance. This challenge was spearheaded by Eliud Kipchoge, the Kenyan marathon runner who is widely regarded as the greatest marathoner of all time.
Kipchoge attempted this feat on October 12, 2019, in Vienna, Austria. The marathon distance, 42.195 kilometers (26.2 miles), has long been a grueling test of endurance and speed. Before this challenge, running it in under two hours seemed almost impossible. However, Kipchoge and his team believed that with the right conditions, support, and strategy, it could be done.
The idea of breaking the two-hour marathon barrier had been discussed for years within the running community. It was seen as one of the last great challenges in distance running, similar to Roger Bannister’s famous sub-four-minute mile in 1954. For many, it wasn’t just about speed—it was a symbol of human potential and the ability to push beyond perceived limits.
A sub-two-hour marathon requires running at an average pace of about 4 minutes and 34 seconds per mile (or 2 minutes and 50 seconds per kilometer) for the entire race. This pace is incredibly fast, even for elite runners. To put it into perspective, most recreational runners struggle to maintain that pace for a single kilometer, let alone for an entire marathon.
To achieve this monumental goal, every aspect of the INEOS 1:59 Challenge was meticulously planned. The course in Vienna was chosen for its flat terrain, mild climate, and consistent conditions. The event took place on a looped course along the Prater Hauptallee, a long straight road in Vienna’s Prater Park. This allowed for precise control over conditions and a consistent pacing strategy.
Eliud Kipchoge was supported by a team of 41 pacemakers, many of whom were elite runners themselves. These pacemakers rotated in and out during the race, ensuring that Kipchoge always had a group around him to maintain a steady pace and reduce air resistance. The pacemakers ran in a V-formation, similar to how geese fly in formation, to minimize Kipchoge’s energy expenditure.
Kipchoge also wore specially designed Nike ZoomX Vaporfly shoes, which were engineered to maximize energy return and efficiency. The shoes became a topic of discussion in the running community, with some questioning whether they gave him an unfair advantage. However, the shoes were within the legal limits set by World Athletics at the time.
In addition to the pacemakers and shoes, a number of other technological and scientific elements played a crucial role in the challenge. For example, a pace car equipped with a laser-guided system projected a green line on the road to guide Kipchoge and his pacemakers, ensuring they stayed on track with the required pace.
Nutrition and hydration were also carefully managed. Kipchoge took on fluids and carbohydrates at specific intervals, ensuring he maintained energy levels and avoided dehydration or glycogen depletion.
The weather conditions were closely monitored in the days leading up to the event, and the start time was adjusted to ensure the most favorable conditions. The temperature, wind speed, and humidity were all optimized to give Kipchoge the best possible chance of success.
On October 12, 2019, Eliud Kipchoge made history. He completed the marathon distance in 1 hour, 59 minutes, and 40 seconds. With this, he became the first human to run a marathon in under two hours. It was a moment of triumph not only for Kipchoge but for the entire running world.
However, it’s important to note that the INEOS 1:59 Challenge was not an official race, and therefore Kipchoge’s time is not recognized as a world record by World Athletics. The use of rotating pacemakers, the controlled course, and the presence of a pace car disqualified it from being considered a legitimate record. Nevertheless, the achievement was celebrated globally as a remarkable human endeavor.
The INEOS 1:59 Challenge has had a profound impact on the world of running. It has inspired countless runners, both elite and amateur, to push their limits and strive for their own personal bests. It also sparked discussions about the role of technology in sports, particularly in the context of running shoes and race conditions.
For Eliud Kipchoge, the challenge solidified his legacy as one of the greatest athletes of all time. His calm demeanor, unwavering belief in his abilities, and mantra of “No human is limited” resonated with people around the world. The challenge also highlighted the importance of teamwork, as Kipchoge consistently credited his pacemakers and support team for helping him achieve this historic milestone.
The INEOS 1:59 Challenge has undoubtedly changed the landscape of marathon running. While Kipchoge’s sub-two-hour marathon was achieved under controlled conditions, it has set a new benchmark for what is possible. Elite runners are now closer than ever to breaking the two-hour barrier in a traditional race setting.
Advances in training techniques, nutrition, and technology will continue to push the boundaries of human performance. The INEOS 1:59 Challenge has shown that what once seemed impossible can become a reality with the right combination of preparation, support, and determination.
In the years to come, the question will no longer be whether a sub-two-hour marathon is possible, but rather who will be the first to achieve it in an official race. Until then, Eliud Kipchoge’s incredible feat will remain a testament to the power of the human spirit and the relentless pursuit of excellence.
