If you want to see just how good a shape you are go to a four day big money race. At 65 years old, fat, and out of shape you have to learn the game and pray you have a motorhome. Usually you get one time trial early in The weekend so take lots of notes on wind and weather. Engine warmups start at between 7-8am and racing usually goes till 4am the next day. Usually I win first round so with buy-backs you probably have 4-5 hours till your next round (if you did win). For use old timers that’s nap time. Second round still a nice break then all heck breaks lose. Bad oil down, nap. Lol. When your day ends you still hear racing into the late hours and at 7am go again for two more days. Then you have the privilege to load up and drive home. I love it but it’s not easy.
