149. Big Al's led the most laps in a career.
Unser, Sr. was in front for 644 circuits before he hung it up.
150. Billy Arnold led the most laps in a single race.
Arnold was in front for 198 laps in 1930.
151. That's also the most led by a winner, by the way.
Billy took the lead after lap 2 and never looked back.
152. Dan Wheldon set the record for fewest laps led by a winner.
Wheldon only led the lap that ended in checkered in 2011.
153. Ralph DePalma holds the record for single-race futility.
DePalma led for 196 laps and didn't win the 1912 500.
154. Rodger Ward led the 1960 race 10 different times and didn't win.
And speaking of single-race futility, that's also a record.
155. And when it comes to career futility — pity poor Michael Andretti.
Over the course of his behind-the-wheel career, Mario's son led a record 431 laps in the 500 without a single win.

Each driver led that race 15 times.
159. Kanaan led in every race from 2002-2008.
Seven consecutive races — another high-water mark for the Brazillian.
160. Rex Mays holds the record for races led without a win.
Mays ran in the clean air in nine different 500s but never saw checkered.
161. The most lead changes at a single race: 68.
2013 was a great year to be in the stands.
162. 2013 also saw the most lap leaders.
A total of 14 different cars ran at the front of the field.
163. The fewest lead changes: One.
Louis Meyer led for two laps in 1930, and then Billy Arnold turned the thing into a parade.
164. Two different races also saw only two lap leaders.
