Let's make this birthday one to remember.

90 years old (Born on March 06, 1935)

Happy Birthday, Ron Delany! You're still running circles around us all—though thankfully now it's mostly metaphorical. Ever since your golden dash in Melbourne back in 1956, you've set the bar so high that even kangaroos are jealous of your leaps and bounds.

From Olympic gold to World Championship bronze medals at 1,500 meters—you've always known how to pace yourself perfectly through life's laps. May this birthday be another victory lap filled with laughter and joy; after all these years you're clearly unbeatable when it comes to inspiring generations (and probably outrunning them too!). Cheers on a timeless champion's special day!
