I’ve been playing with statistics again, plotting winning times at English parkruns against the size of the field. As you might expect, the smaller the field, the greater the variation in winning times.
Before you challenge me about my sample, as I don’t have access to the parkrun database (Dear Jim, please would you fix it for me….), getting my data involved copying and pasting from the results webpages to excel, and frankly, by the time I got to the end of the English parkruns, I’d lost all enthusiasm for the task.
For the purists among you, I’m plotting men’s times and women’s times against the size of the whole field (not men’s times against the number of men and women’s times against the number of women) as this is the information that is easily available.
What do these tell you? If you are a slow runner, your best chance of winning is to attend a teeny, tiny parkrun on a cold, wet miserable day. Which you probably knew anyway.
I really need to get a life!
