With no mountain drama or bunch sprint chaos in the flat
weekend stages of the 2025
Tour de France, the star of the show has been the
oppressive heat. And if the racing wasn’t especially animated, the
behind-the-scenes logistics certainly were, particularly when it came to
hydration.
On Eurosport’s La Montonera, Laura Messeguer broke down the
staggering numbers behind keeping riders cool and functional under the sun, “20
jerry cans per rider, 150 per team, between 1300 and 1500 calories per hour, 2%
of body weight.”
Alberto Contador unpacked those numbers further, pointing to
the brutal effect high temperatures can have on performance. “On a hot day a rider
who is not properly cooled can have their performance affected by up to 15% of
their power, that's a real barbarity,” he said. “It can make you fall behind.
The water bottles are about 5 per hour, 1 and a half or 2 drunk between water
and food and another 3 to pour them over you.”
Contador, who twice won the Tour, underlined how teams now
use meticulous post-stage analysis to monitor riders' hydration. “It is very
important to maintain the body temperature well... In fact, once the runners
finish the stage, in the bus, they have the scales, they are weighed before and
after the stage to see the level of dehydration they have and thus know what
they have to drink to be in the optimal moment of hydration.”
The attention to heat isn’t just about recovery, it’s also
part of long-term planning for what’s ahead. Eurosport commentator Juan
Clavijo, working the Tour’s opening stages, explained that the teams have
already shifted focus toward Monday’s demanding stage in the Massif Central.
“There have been a lot of comments from the cars to the
riders reminding them to hydrate, not to forget,” Clavijo said. “And they have
referred a lot to Monday's stage... It's a very demanding day with more than
4,000 meters of elevation gain and no rest.”
Contador closed the segment by noting that while adaptation
to heat or cold is part of training, some riders are simply built for one or
the other. “I think there are riders who do well in the cold and others who do
well in the heat... There are always cyclists who do well in the heat. I've
seen Pogacar also do well in the heat, but everyone agrees that Vingegaard
handles the heat better than Pogacar.”
