Marathon runner dies after crossing finish line in Singapore

In recent years, there have been notable incidents related to marathon running, including the deaths of two men in their twenties due to cardiac causes after finishing half-marathons in 2011 and 2016. These events have raised concerns regarding the safety of marathon running and the need for health screenings. Experts, including Professor Roger Foo from the National University Heart Centre in Singapore, advocate for health checks prior to participating in marathons. They emphasize that even those who are physically fit should undergo screenings to ensure they can handle the stress of long-distance running. Health screenings are recommended to assess heart health, with options including exercise stress tests and transthoracic echocardiograms (TTE). The exercise stress test costs between $200 and $500 and measures heart response to increased physical demand, while TTE assesses heart structure via ultrasound and costs $400 to $1,000. These assessments can provide valuable insight into a runner's cardiovascular fitness and help prevent potential risks associated with marathon participation. In terms of preparation for a marathon, it is advised that aspiring runners hire a coach for guidance. Training should be progressive, allowing the body to adapt and enhance cardiovascular capacity over time. Experienced runners recommend being able to run for two to three hours weekly, as this is a significant indicator of one's readiness to participate in a marathon. A distance of at least 35 kilometers is also highlighted as essential in ensuring fitness for such a grueling race. During marathons, maintaining adequate hydration and electrolyte levels is crucial. Runners are reminded to refuel at hydration stations or carry their own supplies to avoid exhaustion or heat-related issues. Awareness of physical limits is vital, as ignoring symptoms of heat stress—like cramps and disorientation—can lead to severe consequences, including heatstroke. Experts warn that exerting oneself beyond capability increases the risk of cardiac events, emphasizing the necessity of adequate preparation and health checks before the race.
