Helio Castroneves didn’t need any more prompting than the year: 2007.

“The other day I was thinking about that and was like, ‘Son of a gun,’” Castroneves told Front Office Sports. “With the rain, we thought we had calculated perfectly. You remember those races.”

Castroneves finished second at that 2007 Indy 500 behind Dario Franchitti as the race—which had been paused for nearly three hours earlier in the day due to rain—was cut to 415 miles as rain drenched the famed 2.5-mile oval. Castroneves, already a two-time champ at the time, has won twice more since. He’ll start 20th this time around in the 33-car field as the Brazilian seeks a record fifth Indy 500 title.
