The 13th International 500-Mile Sweepstakes Race was held at the Indianapolis Motor Speedway on Saturday, May 30, 1925.
Race winner Peter DePaolo became the first driver to complete the 500 miles in under five hours, and have an average over 100 mph.
On lap 106, DePaolo came in for relief from Norman Batten while his bloody, blistered hands were bandaged.
The front wheels providing good grip in the turns, Lewis began to pull away.
At about 400 miles, Lewis began to slow, physically exhausted from the grind over the bricks.
