When Raiders of the Lost Ark hero Indiana Jones said, “It’s not the years, it’s the mileage,” I thought about this. I realized that my turning over the young or silly horses to the younger trainers was not an admittance of defeat. Bundling up in my heated vest and cutting hours on a full schedule are not signs of weakness. No longer running marathons does not mean I lost interest in running. These concessions are just efforts to increase my own shelf life.
