Sabastian Sawe World Record 1:59:30 – How Maurten Fueling Made Marathon History
marathon running changed forever. The clock stopped at 1:59:30. The first official sub-2 marathon in history. But behind the Sabastian Sawe world record lies more than talent, training, and race execution. There is one decisive factor that is increasingly defining performance at the highest level: nutrition.
This is the story of how Maurten, combined with a scientific and uncompromising approach to fueling, helped Sawe push the limits of human performance.
Sabastian Sawe Marathon Preparation – From Talent to Total Control
A new generation led by Sabastian Sawe
Sabastian Sawe has long been recognized as an exceptional athlete. Anyone who has trained with him in Kapsabet, Kenya, has seen it firsthand. But he represents something more than raw ability. He is part of a new generation of East African runners who approach performance with precision.
How Maurten supported Sawe’s marathon build-up
What sets Sawe apart is not just how he runs. It is how he optimizes every variable that impacts performance. In that process, Maurten became fully integrated into his team in the build-up to the 2026 London Marathon.
Over twelve months, they worked together with a single objective. To build a fueling strategy capable of sustaining a pace below 2:50 per kilometer.

Data-driven performance for Sawe’s world record
Reaching that level required more than traditional sports nutrition. The work went far deeper.
Maurten’s team conducted extensive testing to understand exactly how Sawe’s body produces and utilizes energy. This included analysis of VO2 max, running economy, lactate levels, and total energy expenditure. They also used advanced methods to measure how efficiently his body could absorb carbohydrates during exercise.

At the same time, they monitored training load, body composition, and thermoregulation. Every data point contributed to refining both training and nutrition.
This was not about assumptions. It was about certainty.
“Training the Gut” – How Sabastian Sawe Reached 100+ g Carbs per Hour
From 60 to 115 grams – redefining fueling limits
One of the biggest historical limitations in marathon running has been the gut. How much energy can the body actually absorb at race intensity without breaking down?
For years, 60 grams of carbohydrates per hour was considered the upper limit. For a sub-2 marathon, that is not enough.
Gut training in the Sabastian Sawe marathon plan
The solution was systematic gut training. Over months of structured sessions, Sawe conditioned his body to tolerate increasingly higher carbohydrate intake. Every long run became an opportunity to practice his race fueling protocol, using Maurten Gel and Drink Mix at precise intervals.
The goal was to improve absorption while minimizing gastrointestinal distress.
The result was an average intake of 115 grams of carbohydrates per hour during the race. A level that would have been considered impossible not long ago.

Maurten Hydrogel Technology – The Key to Sabastian Sawe’s Fueling Success
How hydrogel enables high-carb intake in marathon running
At the core of Sawe’s fueling strategy is Maurten’s patented hydrogel technology. It fundamentally changes how the body handles carbohydrates during exercise.
When mixed with water, Maurten’s Drink Mix forms a hydrogel in the acidic environment of the stomach. This gel encapsulates the carbohydrates, allowing them to pass through the stomach without triggering the issues typically associated with high-carb intake.
Why Sabastian Sawe could fuel without GI issues
Instead of lingering in the stomach, the energy is transported to the intestine, where absorption is more efficient. This enables athletes to consume significantly higher amounts of carbohydrates while maintaining comfort and stability.
For Sawe, this meant a continuous and reliable energy supply at a pace where even small disruptions can have major consequences.
Maurten Bicarb System Explained – Sabastian Sawe’s Race Day Advantage
What is the Maurten Bicarb System?
While carbohydrates fuel the engine, managing acidity is critical when operating at the edge of physiological limits.
During high-intensity efforts, the body produces hydrogen ions that contribute to muscular acidosis, often experienced as fatigue and loss of power. Sodium bicarbonate has long been known to buffer this effect, but traditional delivery methods frequently cause severe gastrointestinal distress.
Maurten’s Bicarb System changes that.
How the Bicarb System helped Sawe’s world record performance
Using hydrogel technology, bicarbonate is encapsulated and delivered through the stomach more effectively. This reduces the risk of GI issues while allowing athletes to benefit from higher doses.
On race morning, Sawe used the Bicarb System as part of his protocol. The goal was clear. To enhance his body’s buffering capacity and delay the onset of fatigue during the most demanding phases of the race.
In a performance decided by seconds, this marginal gain becomes decisive.

Sabastian Sawe Race Day Fueling Plan – Step by Step
Pre-race fueling before the Sawe marathon record
On race day in London, nothing was left to chance. Every minute and every gram of energy was planned.
The process began two days before the start with carbohydrate loading using Drink Mix 320 to maximize glycogen stores. On the morning of the race, Sawe kept his intake light, followed by the Maurten Bicarb System to support high-intensity output.
In-race fueling strategy during the Sabastian Sawe marathon
Just before the start, he topped up with additional fuel. During the race, he followed a strict schedule of fluid and gel intake at specific distances, ensuring a constant flow of energy without spikes or crashes.
This level of precision enabled him to maintain an aggressive, even pace all the way to the finish line.
Why Sabastian Sawe’s World Record Changes Marathon Fueling Forever
Nutrition as the fourth discipline in marathon running
Sabastian Sawe’s world record is more than an individual achievement. It is proof of how critical nutrition has become in endurance sports.
Training, race strategy, and equipment have long been key factors. Now fueling stands alongside them as an equally important pillar. The ability to absorb and utilize energy in real time can determine whether an athlete maintains pace or fades.
What runners can learn from the Sawe marathon strategy
With the right fueling strategy, limits are no longer fixed. They can be redefined.
The Future After the Sabastian Sawe World Record
1:59:30 is not the end of an era. It is the beginning of a new one.
What was once considered impossible is now reality. And behind that reality lies a clear insight. Peak performance is not only about how fast you can run. It is about how effectively you can fuel the effort.
For Sabastian Sawe, that made the difference between an extraordinary performance and a historic moment.
For the rest of the running world, it sets a new standard.
