Nick Goepper, a two-time Olympic ski slopestyle medalist, will be at least the second Olympian to be the grand marshal of the Indy 500.
Goepper, an Indiana native, will give the command for drivers to report to their cars during pre-race ceremonies. In 2015, Olympic champion gymnast Nastia Liukin was the Indy 500 Grand Marshal, taking a parade lap around the 2.5-mile oval before the start.
Cyclist Lance Armstrong drove the Indy 500 pace car in 2006.
In 2014, Sochi medalists figure skater Gracie Gold, bobsledder Steven Langton and Goepper made VIP appearances at the Great American Race.
