Stay Focused with appropriate Hydration
Driving at high speeds with temperatures of more than 140 degrees Fahrenheit inside the cockpit is challenging, you need to stay focused.
In summer, you can loose at least 1-2 pounds for every 30 minutes race, that can decrease your performance and your focus.
Every race car driver prepare the machine and push the driving to the limit to gain 10ths of seconds per lap, not having an appropriate Hydration System can generate a lost of that gain and more.
Driving at slow speeds during yellow flags reduce the ventilation and raise all the temperatures, the cockpit, your body, reducing the capacity to focus in your driving performance. You need to low your body temperature in that condition.
The Hydration System is not a replacement for a good physical condition, it is a complement to improve your driving performance
