Tour De France 2021 - Data Doodles - Week 1

Following on from last year's posts (week 1, week 2 and week 3), I am doing the same thing this year.

The post has been delayed by real life, football and fencing.  (Fencing's back, let's do the dance of joy)

These visualisations cover week 1, which was nine days long because *shrug* Tour de France organisers.

Most of the withdrawals were mid-stage abandonments, but there were a lot, more than a 3rd of the total, that were riders outside the time limit

By the end of "week" 1, Groupama-FDJ were the worst affected team, losing 40% of their riders,

That most of the team withdrawals were on stage 9 is clearer to see on the total riders version of the diagram

But stage 9 happened to a lot of people (seriously TDF organisers, WTF?!)

Quite how large a chunk of the withdrawals came on stage 9 can be better seen in this image.

You can see stage 9 happening to the teams in the individual team Kaplan-Meier diagrams.


You can see stage 9 happening in the overall Kaplan-Meier too

But, is the overall attrition rate any worse than last year?

Not particularly, although the fact that the rate was slightly higher might affect teams more and increase the total attrition rate at the end of the race.  (Spoiler, after two days of week 2, it has.  But I think that has more to do with today's stage.  Again, TDF organisers, WTF?!!)
