It's hard to determine which is the bigger event. Suffice it to say that with the American motorsports world, the Indianapolis 500 and the Daytona 500 tower over anything else.
Both are more about a month than a day. And both feature tremendous buildup to one 500-mile battle.
In short, both are the crown jewels of their sports.
"It certainly is a big event," Jeff Burton said of The Great American Race. "As the sport has grown, it's become more and more a big event."
Both races have a deep history to lean on, as well.
"The fact that it's been going on 86 years. It's the most historic race anywhere on the planet, the most documented. It's the single most important motor race in the world," Greg Ray said of The Greatest Spectacle in Racing. "If you go to any third world country and say "Indy 500" in any language, and people know what it is.
"I think the documentation of this race the last 50 years and as time goes on and society changes, this is one constant. There is not going to be something new come along that will replace these events. Until they start racing space shuttles across space, this will still be the race of all races."
But while Daytona and NASCAR have thrived in recent years, the same can't necessarily be said for Indy. Some blame the open-wheel split, most cringe at the small crowds present at the Speedway during May.
Could the event schedule and structure itself play a role? Daytona's Speedweeks are more condensed, while May at Indy really is a month-long event. Daytona also has action every day, while Indy has several off-days, including four the week of the race.
But Dayona's schedule includes several races -- IROC, ARCA, Trucks, Busch, Bud Shootout, Gatorade 125s -- in addition to the 500. This year's Infiniti Pro Series debut marks the first time another race was held at Indy during May. And while many purists were angered about the inclusion of a minor league series, it seems Indy tradition might need some tweaking.
This year's Indy field is good, but the lack of extra cars took the drama out of Bump Day. NASCAR, meanwhile, has Speedweeks so jam-packed that it's easy to find excitement.
So maybe the Indy 500 is turning into a one-day event. Possible solutions? Condense the schedule or add more events. And if other series racing at Indy during May doesn't float your boat, what about Bud Shootout-like races under some lights? That would surely attract huge crowds.
Indy might not be what it used to be, but it's still a great event. And despite what else happens in May, fans likely will go home happy on the 25th -- that is, if weather or ill-timed cautions don't get in the way.
