Charting the Tour: What the data shows us as the race into the Alps



We are well into the third week of the Tour de France and have no idea who will win the race – we still have a few mountain stages to do before we realize that.

This year's race Cameron Harris, VeloClub member, has transformed the data from the Tour de France results into interesting charts and graphs to look at the world's biggest race from a different perspective. With these diagrams we can show storylines that we would not otherwise see, and better understand the meaning of certain driver performance.

All images below are screenshots taken from the site of the Tour de France visualization center. Here are interactive versions of these graphics and more, all updated daily. And if you have not already done so, take a look at our breakdown of the first 1

0 stages of the race.

After 16 stages you will easily see the following in the tour charts.

Thibaut Pinot will do it ruining his time losses on the 10th stage.

As Neal Rogers wrote earlier in the week, Thibaut Pinot would finish second overall (10 seconds behind Alaphilippe), if those annoying crosswinds on Stage 10 were not the best climber in the tour and the trajectory of his Line in the GC position swarm card shows this.

Since the tenth stage, Pinot has gained time on each mountain stage. Provided he can deal with the heat, a podium (or even a win) is quite possible.

Tony Martin is the biggest "swinger" in the race.

Martin is the driver with the biggest differences in GC rankings throughout the tour. He was fourth after the team time trial of the 2nd stage and only two days later 172 years old. Notice that he is now in 160th place … mainly because a good many riders have given up.

Martin was in the runaway and finished the race nine minutes ahead of the peloton, which made him nearly 40 places in the overall standings.

An honorable mention in the "Big Swinger" category goes to Kasper Asgreen, whose highest ranked 12th and lowest ranked 176th place on consecutive levels (Levels 2 and 3). It's no coincidence that both he and Martin had similar roles on the tour – they drove heavily in TTT for their GC rivals, then spent hours on the front of the group on the flat stages before breaking off and loosening it up to the goal.

35 riders have been in the top 10 of this tour so far.

Note that Richie Porte is the youngest newcomer to the top 10 club thanks to Jakob Fuglsang's unlucky departure on the 16th.

No one was in the top 10 in all 16 stages. Geraint Thomas, Steven Kruijswijk and Egan Bernal spent most of their time in the top 10 with 15 stages each.

Alaphilippes advantage is still considerable with five remaining stages In the time trial of the 13th stage, he was able to extend his lead with a victory, and on the 14th Stage Thomas lost again a little time in Tourmalet. As you can see in the graph of the GC swarms below, Alaphilippe's lead went down on the 15th stage (this is the horizontal line at the top of the map.)

Three difficult days in the mountains make it " Loulou "difficult to keep yellow. But we said that before the time trial and the Tourmalet, right?

The second to sixth place on GC are very close together.

Alaphilippe leads Thomas 1:35 after the 16th stage. but from thomas to emanuel buchmann in sixth place is only 39 seconds. This is a close argument over the podium, especially considering that Alaphilippe will likely fall off the podium by the end of the 20th leg.

Note the significant gap of Buchmann in sixth place to Mikel Landa in seventh. That's 2:40, 36 seconds more than the distance from the first to the sixth.

Here is another way to see how closely the drivers are grouped from second to sixth:

There is a massive gap between the 17th and 18th

First through 17th. (David Gaudu ) is 15:33. From the 17th to the 18th (Romain Bardet) it is still 13 minutes. This is by far the biggest time gap between consecutive positions in the race, even considering the positions at the very back of the field.

Here's another way to visualize this gap:

How can we explain this big gap? Looking back at the GC time swarm over the tour, Level 6 seems to have done the damage. It reduced a large group of riders near the top of the GC to a select group and created a large gap between these top 30 and the rest of the field.

We've seen a group of GC riders retire this leader since – Guilio Ciccone, Romain Kreuziger and Alexey Lutsenko, for example – but as you can see below, we really did not see anybody who lost time at level 6 ,

Yoann Offredo seems to have gotten better.

On the last day of rest, we wrote about how Yoann Offredo did badly and how he came in last in the overall standings, more than 20 minutes behind the second slowest rider. Well, the Frenchman is still the last, but the gap has narrowed considerably.

This narrowing is mainly due to Sebastian Langeveld, who put some serious time into downtime. He is now just three minutes from Offredo, 3 hours, 12 minutes and 46 seconds behind Alaphilippe.

Could we see a dispute over the lantern rouge as Paris nears?

The battle for the points jersey podium heats up.

Ok, there is no podium for the points score, but let's just do it. Elia Viviani finished second on stage 16 and overtook Sonny Colbrelli and Michael Matthews. The stage win by Caleb Ewan also puts him in fifth place behind the wheel of Matthews. In fact, only 26 points separate only the second from the fifth – about the equivalent of second place on a sprint stage.

Of course, the green jersey Peter Sagan belongs. But the fight behind it is still pretty interesting. Do people like Viviani and Colbrelli score points if Sagan breaks out of the tour?

It is mathematically possible that Sagan will finish the tour and not win green, but it is very unlikely. Viviani could go green when he wins the Champs-Elysées, win two intermediate sprints … and if Sagan scores no points for the remainder of the tour. As long as Sagan scores any points from now on, he wins green.
