In the meantime, as I've said repeatedly, we continue to advise the following on race day:
1. Take a baby aspirin (81mg) the morning of the event.
2. Limit caffeine that morning to less than 200 mg.
3. Take the last mile like the previous without a fast sprint.
These recommendations make sense to me and my fellow marathon medical directors. When our patients ask us, "How can I prevent becoming the next one?" our advice - right after urging them to get a comprehensive physical - consists of the three steps listed above. I hope you follow this advice, in conjunction with your physician, as well.
