With 83% of the race completed, some of the highlights of the 16 stages include:
- The average speed of riders across the 16 stages was 39.16 km/h, while Tour de France leader, Chris Froome recorded an average speed of 40.21 km/h. In the first nine stages of the Tour, Froomes average speed was 39.67 km/h.
- Dumoulin (TGA) recorded the fastest average speed of 44.78 km/h during an individual time trial on stage 13.
- During the 16 stages which covered 2,922 km, riders were affected by severe wind gusts of up to 80 km/h.
- On stage 9, hail during the last 5 km of the final climb (average gradient 7.2%) caused the speed to drop by 31%.
- When Julian Alaphilippe (EQS) crashed 15 km from the finish in the individual time trial, it was at a speed of 51.7 km/h with crosswinds of 42 km/h.
- 47.0 km/h was the highest average speed on stage 10, which is an increase on the highest speed in stage 1 (44.35 km/h).
This year Dimension Data and Amaury Sport Organisation (A.S.O.) introduced the tracking of weather conditions. The wind on Mont Ventoux (stage 12) raged at 140 km/h, which caused the race organisers to move the finish line and shorten the stage distance by 6 km. This climb is also the toughest, based on gradient, elevation and weather conditions. Thomas DeGendt (LTS), clocked an average climbing speed of 14.8 km/h, while the lowest recorded climbing speed on Mont Ventoux was 12.72 km/h.
Dimension Datas mobile data centre and office has travelled 3,858.5 km since the race began on 2 July. The 39 tonne truck accommodates the 22-strong on-the-ground technical, social and support team. And to follow the race, there are 10 screens in the truck, which takes two hours to set up and take down every day after each race is completed.
