66 years old here and my body is pretty beat up from 33 years of millwright work in a steel mill. I raced three out of four weeks every month this summer and work hard at thinking I’m 29 years old. I’ve learned a few tricks that really help with three day Rae’s in 90 degree weather. If you can sit, sit. Stay out of the sun between rounds as much as possible. And watch the alcohol. I do 100% of everything on my car and race by myself so you have to use your head. We aren’t 16 anymore.
