I've had the privilege of driving in various endurance races, including the 24H/Daytona. I've also driven in the TransAm series with a large and hot V-8 stuffed next to my right ankle.
Judge... you are 100% right about the temperature.
My crew chief put a pyrometer in the cockpit of our TransAm car at the San Jose Grand Prix in 2006. The race was 2 hours long and it reached 174 degrees. I lost 8 pounds that weekend. I was lucky -- I had started to hydrate myself 2 weeks earlier and had built up a lot of cardio stamina. After the race, 5 drivers went to the medical center for I.V.s and care.
Two weeks later, we did the same at the Denver GP (5,800 feet in elevation). 181 degrees in the car.
The worst was Las Vegas, running in August (how stupid is that) on the road course inside the big oval. 192 degrees for a 2 hour race. The drink water was damn near boiling. The cool suit was worthless after 45 minutes.
The only comment I would make is that I would offer my opinion that higher humidity sucks the energy from you faster than low humidity. There appears to be a Sierra Nevada-based storm and barometric low-pressure system hovering nearby this week that has raised the humidity level.
Reno-Fernley is going to test the metal of some drivers. I just hope that we are all "smart drivers" and know when to end our stints because of fatigue, rather than trying to push through because our timeline isn't over.
Good luck to all -
