Singer Cody Simpson and Radio Disney host Alli Simpson made headlines in Rio de Janeiro on Friday with a brother-sister moment that was nothing short of gold. The Australian siblings invited fans to watch them run with the Olympic Flame in Rio's Ipanema Beach on the final day of the Olympic Torch Relay.

“It’s one of those things that falls so far outside of anything that you could ever imagine yourself being presented with… an opportunity like that is really one of those once in a lifetime opportunities,” Cody said. 

Cody and Alli are part of Coca-Cola’s global group of #ThatsGold social media influencers for the Rio 2016 Olympic Games. Their role? To bring #ThatsGold Olympic moments to fans around the world by posting their experiences on social media and inviting their networks to join the fun.

After finishing their early-morning 200-meter runs, Alli shared the surreal experience with her 1.7 million Instagram, 1.1 million Facebook and 1.5 million Twitter followers in an emotional post: 

Cody also took to social media to share his #thatsgold moment with fans:

Cody and Alli were two of 12,000 torchbearers who carried the Olympic Flame across 329 cities in Brazil over a 95-day period. Get a sneak peek of their experience moments before they stepped out of reality and into an Olympic dream come true:

Following the Olympic Torch Relay, the Simpson siblings attended the Rio 2016 Olympic Games Opening Ceremony that night. The next day, they hit the pool to cheer on the Aussie swim team, many of whom are Cody’s mates. (Fun fact: Before his musical career took off, he was a competitive swimmer, winning two gold medals at the Queensland Swimming Championships.)
