Alex Yee is back in the spotlight this weekend, and not only because of the London Marathon. The Olympic gold medallist has put a surprisingly simple food at the center of his race routine: the banana. In a sport often associated with cutting-edge supplements and tightly managed fueling plans, alex yee has highlighted how plain, familiar foods still matter. That detail is striking because it sits beside a far more technical approach to endurance, one that has helped him build a reputation as one of Britain’s most compelling distance runners.
Why Alex Yee’s routine matters now
This Sunday’s race places Yee in a star-studded field in his home city, with expectations shaped by both his Olympic success and his rapid rise over the marathon distance. He only ran his debut competitive marathon in 2025, yet he already sits second on the British all-time list behind Sir Mo Farah. That makes his return more than a routine appearance: it is a measure of how quickly his endurance profile has developed.
What stands out is the contrast between precision and simplicity. Yee has described a pre-race routine built on carbs, gels and a supplement called Bicarb, but he also relies on plain rice, honey and banana before racing. In a discipline where small mistakes can ruin a race, that balance between performance science and low-risk food choices is part of the story.
The science behind a 16p staple
For Yee, the banana is not a gimmick. It fits into a broader strategy focused on avoiding discomfort while still getting enough fuel in. He has said the days before racing involve plain white rice with one protein source such as chicken or salmon, and that the morning of the race includes plain rice with honey and banana. The logic is straightforward: keep the stomach calm, keep the carbs coming, and avoid unnecessary surprises.
That practical thinking is echoed in research from the University of Waterloo in Canada. Professor Anita Layton said that adding more potassium-rich foods such as bananas or broccoli may have a greater positive impact on blood pressure than only cutting sodium. The university’s model examined the body’s potassium-to-sodium balance and included differences between men and women. Doctoral candidate Melissa Stadt said the findings made public in 2025 suggest that early human diets may help explain why modern systems respond well to a high-potassium, low-sodium pattern.
For alex yee, the relevance is twofold: the banana is part of race preparation, and it also happens to be linked to a wider conversation about health that reaches beyond elite sport.
What lies beneath the headline
There is a deeper reason this story resonates. Marathon performance is often presented as a contest of suffering, but Yee’s approach shows how much of elite endurance is about minimizing risk. The routine he has outlined over 18 months of racing includes carbs on the bike, gels during the run and Bicarb to help with lactate. That combination suggests a highly managed effort to extend his ability to push hard for longer.
At the same time, the emphasis on “safe food without any risk of discomfort” reveals why the banana matters. It is cheap, accessible and predictable. In elite sport, predictability can be as valuable as novelty. That is especially true for an athlete returning to a major race in a home environment, where expectations are high and the margin for error is slim. The attention around alex yee is therefore not only about his medal record, but about the disciplined habits that support it.
Expert views on blood pressure and performance
The strongest institutional view in the available material comes from the University of Waterloo. Professor Anita Layton’s assessment is careful rather than absolute: more potassium-rich foods may have a greater positive impact on blood pressure than simply reducing sodium. That framing matters because it avoids overstating the effect of any single food.
Melissa Stadt’s contribution to the university’s findings adds another layer. The model’s suggestion that modern Western diets are much higher in sodium and lower in potassium supports the idea that the banana is not just athlete fuel, but part of a broader dietary pattern with public-health implications.
For the marathon context, those points do not mean a banana alone drives performance. They do, however, reinforce why Yee’s preference feels credible. His choices align with both a race-day logic and a health logic, which is part of why fans pay attention when alex yee explains what he eats.
Broader impact beyond one marathon
The wider significance is that Yee’s routine bridges two audiences at once: marathon followers and everyday readers interested in blood pressure and diet. His approach shows how elite sport can make ordinary foods feel newly relevant. It also gives a clear example of how high-performance habits are often rooted in restraint rather than excess.
In a field filled with elite names, his return to London is likely to be judged by time and placing. But the story around his preparation adds another measure: whether a simple banana, a careful carb plan and a strict pre-race routine can help a runner already near the top of the British all-time list go even further.
As the race begins, the question is no longer just how alex yee will perform, but how much more of elite endurance can still be explained by the simplest food on the table?
