As the excitement builds for the 44th edition of the Rotterdam Marathon set to take place on Sunday, April 13, 2025, the focus is not just on the thrill of the race but also on the potential for record-breaking performances. With approximately 17,000 runners gearing up to tackle the grueling 42-kilometer course, the atmosphere is charged with anticipation and a hint of anxiety regarding the weather conditions.
Former marathon runner Michel Butter has expressed a keen interest in seeing a new women's record set during the event. The current record, standing at 2:18:56, has remained unbroken since 2012, and Butter believes it’s time for a change. "That record has stood for far too long. It was set in an era before we had the carbon shoes that enhance performance," he stated emphatically.
On the men's side, the record is held by Bashir Abdi, who completed the marathon in 2:03:36 in 2021. Unfortunately, Abdi will not be competing this year due to an injury, leaving the field open for other contenders. However, the potential for record-breaking performances hinges on several factors, including the course layout, the caliber of the participants, and, crucially, the weather conditions.
This year, the marathon organizers have made a significant change to the course by removing a challenging 180-degree turn that previously occurred between the 13th and 15th kilometers. This alteration is expected to shave off precious seconds. Racedirecteur Marc Corstjens noted, "You essentially come to a standstill at such turns, losing momentum and rhythm. I promised the top athletes that we would make the course faster, and this change is a step in that direction."
However, Butter cautioned that while the course modifications are beneficial, the weather remains a critical factor. He explained, "It can’t be too warm. If temperatures rise too high, your core temperature increases, and your body focuses on cooling down instead of maintaining speed. Ideally, temperatures should be around 10 degrees Celsius, but we expect it to be between 13 and 16 degrees on race day. While not perfect, it's manageable as long as the sun stays hidden."
The forecast for race day indicates temperatures starting at 13 degrees and potentially reaching 16 degrees by the finish. Adding to the challenge, wind conditions are predicted to be moderate, with gusts expected to hit runners as they approach the final kilometers of the race. Butter acknowledged, "Wind is another crucial factor. If runners face headwinds after 34 kilometers, it could impact their speed and endurance significantly."
As the marathon draws near, the elite field of competitors is also a point of focus. Butter highlighted the presence of Geoffrey Kamworor, a two-time New York Marathon champion, as a significant addition to the lineup. "Having a runner of Kamworor's caliber adds excitement. It would be fantastic to see a New York winner take the title in Rotterdam," he said.
While the emphasis is on breaking records, Butter reminded fans not to be disheartened if times fall short. "If conditions aren’t ideal for record-breaking, I hope to see an exciting race with competitors pushing each other in the final stages. It’s all about the competition and the thrill of racing against one another."
On a more serious note, the health risks associated with marathon running have also come into sharp focus, particularly concerning heat stress. Dr. Jelmer Alsma, an internist and part of the medical team at the marathon, explained that while training for a marathon is generally healthy, the actual race can pose significant health risks, especially in warmer conditions.
Dr. Alsma noted, "There’s no clear answer on whether running a marathon is healthy for everyone. For some, it’s beneficial, while for others, it can be life-threatening. Runners must listen to their bodies and adjust their pace or withdraw if they experience any issues. Many finishers come across the line exhausted or even vomiting, especially when treating the marathon as a competition."
Heat-related illnesses are a particular concern, especially if temperatures rise during the race. "The most dangerous condition is exercise-induced heat stroke, which occurs when body temperatures exceed 40 degrees Celsius. Last year, over 80 runners suffered from heat stroke, and in 2019, there were 252 incidents of heat-related issues when temperatures reached around 21 degrees," Dr. Alsma warned.
To mitigate these risks, Dr. Alsma emphasized the importance of preparation and self-awareness. "Runners need to train not just their endurance but also acclimatize to higher temperatures. If you’ve trained in cooler conditions, you must adjust your expectations on race day if it turns warm. Proper hydration is crucial both before and during the race."
In case of emergencies, the marathon will have a robust medical presence along the course, with around 150 medical personnel and ten ambulances ready to assist. Dr. Alsma reassured participants, saying, "We are prepared to handle any incidents. Our goal is to keep runners safe, and we encourage spectators to help by cooling down any runners who appear unwell. Using water bottles or wet cloths can be effective, and if someone is in serious distress, calling emergency services is vital."
As the countdown to the Rotterdam Marathon continues, athletes and spectators alike are reminded of the excitement and risks that come with this iconic event. With the potential for record-breaking performances and the ever-present health considerations, this year’s marathon promises to be both thrilling and challenging.
