Running a 4 hour marathon at 75+ is insane work
made in RStudio by scraping the multisport Australia website. My favourite part of this visualisation is overlaying two separate geom_points to create a glowing look with a bright dot surrounded by a faint little halo. 🙂
library(rvest)
library(tidyverse)
marathonresults <- vector(mode = „list“, length = length(242))
for (i in 1:242){
marathonresults[[i]] <- paste0(„https://www.multisportaustralia.com.au/races/melbourne-marathon-2025/events/1?page=“, i)
}
marathonresults <- unlist(marathonresults)
marathonresults2 <- vector(mode = „list“, length = 242)
for (i in seq_along(marathonresults)){
marathonresults2[[i]] <- read_html(marathonresults[[i]]) %>% html_table()
}
stragglers<- read_html(„https://www.multisportaustralia.com.au/races/melbourne-marathon-2025/events/1?page=243″) %>% html_table()
stragglecrew<- stragglers[[1]] %>% select(-8) %>%
filter(Pos!=“DNS“) %>% select(time = `Net Time`, age = `Category (Pos)`)
mara3<- marathonresults2 %>% bind_rows() %>% select(time = `Net Time`, age = `Category (Pos)`) %>%
rbind(stragglecrew)
I wonder how much of the shape is selection bias
That is a really nice graph! You can see the decline by age and speed groups pretty vell, which is a totally fun extra layer of information.
