Ok, just heard on fox that most amateur marathoners hope to come in at 4 hours. So this is obviously planned for max damage and death.
As an ex runner,there would be alot of competitors in the area at the 4 hour mark. The elites would have probably have gone but the average garden variety runner would still be there or just finishing. There is a substantial cool down period after a race and many racers stay to cheer on those that aren’t as fast. To the majority winning doesn’t come into the equation. Its finishing and possibly having a personal best time.
