DePaolo jumped into the lead at the start, withEarl Cooper close behind.Phil Shafer led briefly, but DePaolo returned to the lead by half-distance. On lap 106, DePaolo came in for relief fromNorman Batten while his bloody, blistered hands were bandaged.Dave Lewis then took over the lead in a front-wheel-drive Miller. The front wheels providing good grip in the turns, Lewis began to pull away. Batten soon pitted and DePaolo returned to the cockpit, and set his sights on Lewis.
At about 400 miles, Lewis began to slow, physically exhausted from the grind over the bricks. His crew called him in, but he overshot his pit stall and had to continue for another lap. When he finally stopped, crewmen lifted him out andBennett Hill climbed in, now 1 1/2 laps behind DePaolo after the botched pit entry and eventual stop.
Hill sped after DePaolo, unlapping himself with about 25 laps to go and gaining several seconds with each lap. But DePaolo crossed the finish line with a record sub-5-hour 500 57 seconds ahead of Hill.[3]
