I don't think he had any reason to apologize. He said what he said at the end of the race — a time when people needed to hear it. The rules should change! You either run all three races or you don't run at all. Or, at the very least, there is more rest time between each race. In the scheme of things, it is a small problem, but why not bring some fairness to one thing in the U.S. that appears could be easily fixed.
