God I need to man up. I can’t even imagine 20 straight hours. I feel like my Baja experiences have been the opposite to all the studs on this thread. Typically after my sections done. Say 10 hours in the drivers seat has been pretty standard for me in Baja and doing about 300 miles. No matter morning day or night. I’m dead to the world 10-15 minutes after I get inside the chase vehicle. I don’t know how guys can race, for 10-20 hours then get out and drive and still be able to stay awake and function safely. Especially when you don’t sleep much the night before the race and can’t sleep at all leading up to when it’s time for you to get in the race car.
