When the heat rewrites the race, hydration becomes a performance weapon
With tomorrow's Tour de France stage shortened by 30 kilometres because of the extreme heat, hydration has once again become one of the defining performance factors in modern professional cycling.
For the Pinarello Q36.5 Pro Cycling Team, however, adapting to these conditions is not about reacting on race day. Instead, it is the result of a carefully planned strategy, developed together with nutrition partner Amacx and executed from breakfast until long after the finish line.
Today's stage was a perfect example. While the physical demands were not exceptional from an energy perspective, the soaring temperatures made fluid management the team's primary focus.
"Our priority today wasn't the highest energy intake – it was hydration," explained Head of Nutrition Adam Plucinski. "Our target was around one litre of fluid per hour, while accepting that a small level of dehydration at the finish is perfectly normal and doesn't compromise performance."
According to Plucinski, the biggest mistake riders can make in extreme heat is surprisingly simple.
"No amount of sodium or electrolytes can compensate for insufficient fluid intake. Just as importantly, riders need to drink consistently throughout the stage rather than consuming large volumes at once."
Executing that strategy requires products specifically designed for the demands of elite racing, which is where Amacx plays a central role.
"Amacx is a key partner in our hydration strategy. Their product range allows us to adapt our hydration strategy to the specific demands of each stage. Today, our strategy was one isotonic bottle and one bottle of water per hour, together with all ranges/types of EnergyLine bars, maintaining hydration while avoiding overeating carbohydrates."
The team's work does not end at the finish line. Hydration is monitored before breakfast, riders are weighed before and after each stage, and hydration is assessed again before dinner to determine whether further rehydration is required.
"Every stage ends with data, not assumptions. Those measurements tell us whether a rider has fully recovered or whether the rehydration protocol needs to continue."
As the Tour enters another period of extreme heat, success will increasingly be determined by what happens inside the bottle as much as by what happens on the road.
