To keep participants safe, public health officials recommend attendees keep a distance of at least 6 feet between one another.
this year are from countries with “do not travel” advisories, and these runners will have their entries deferred. Using those numbers, we estimated.The L.A. Marathon begins at Dodger Stadium, where runners typically group into five corrals on a four-lane road that runs alongside the stadium’s outfield side. I used
to estimate the width of that road to be about 44 feet, which fits with general street size guidelines. How many runners can fit, 6 feet apart, on this stretch of road?Seven runners fit across the width of this road, with very little leftover space. We’ll line up all 19,920 runners in rows like this, with 6 feet between each row.So our 19,920 runners form over 2,800 rows of seven, making a total “start length” of about 3.77 miles.
We had one additional whim for how to fit more runners into the starting space. What if we staggered them so the rows were 6 feet apart in triangle form?also mean every other row holds just six runners instead of seven.So there are more than 200 additional rows, but that’s balanced out by how much the length decreases—to a total of “just” 3.48 miles.
If everyone comfortably fit somehow, their rolling start would take hours. Runners would need to follow highway merging procedures when they bottlenecked from four lanes down to two, and even drivers can’t agree about how to do that. The only thing that wouldn’t be a huge issue is timing, because chip timing means each runner can be measured personally from start to finish.
Running a marathon is hard enough, and these challenges would only make the feat that much harder. To any marathoners running this weekend, good luck—and please stay safe.
