Say that you want to run a semi marathon but you’re not sure about how you will perform WRT the average runner. The Sémi Maraton of Paris, with > 30k runners is quite a different story than the Sémi Marathon de Nogent with ~
2000 600 runners. If you’re not fast, you will not be alone in the former, but you will be noticed in the latter.
Solution: download last year’s results and draw a histogram with R.
> res <- read.csv("Desktop/120325_semi_94.csv", header=TRUE, sep=";")
# convert time column to time
> temps <- strptime(res$Temps, format="%H:%M:%S")
# finally plot the histogram
> hist(temps, "mins", freq=TRUE)
Which gives this:
Indeed, this seems a quite fast race, but look at that nice spike around 2:00 🙂
