Ernie Halvorsen and Cindy Chiang have won season 19 of The Amazing Race.
The engaged couple, who finished last week's semi-final in second place, triumphed to claim the $1 million (£639,635) prize on the final leg in Atlanta, Georgia.
Ernie and Cindy revealed after their victory that they intend to use their winnings to help those less fortunate than themselves.
Cindy said: "We would really like to create an organisation that can multiply the $1 million and help those really in need. We have been around the world and have met the most amazing people... They just need a little bit extra and we want to help them and inspire them to live a better life and contribute to the global economy."
Ernie added that their parents had probably "passed out in disbelief" at learning about their victory, while Cindy said her parents always expected her to be "perfect" in all she did, so hopefully she and Ernie had proved they were the best team working together.
Cindy added that the race had been "the best pre-marital counselling you could ever get", while Ernie said he was "proud" of Cindy and couldn't think of anybody else he'd rather spend his life with.
Dating couple Jeremy Cline and Sandy Draghi - who hail from California - finished in second place, having started the season finale in the lead. Former NFL player Marcus Pollard and his wife Amani finished third.
The finalists undertook a series of challenges on the final leg of their journey between Tocumen International Airport in Panama and the pitstop of Swan House in Atlanta, Georgia.
Cindy & Ernie and Jeremy & Sandy had been worried that Marcus & Amani would have an advantage because Atlanta is their hometown.
They had to land an aircraft in a flight simulator, find the home of Gone with the Wind author Margaret Mitchell, complete a roadblock challenge using a broken typewriter and trace their Amazing Race journey on a giant world map.
While Sandy and Jeremy started the leg in first place, they lost their lead to Cindy & Ernie after the flight simulator challenge, where the men acted as pilots and had to land the aircraft from an altitude of 2,500 feet. The woman in each team served as co-pilot, maintaining an air speed of 135 knots.
Cindy & Ernie remained in front from that point, helped by the fact that Jeremy & Sandy made an error in deciphering the second clue, which instructed teams to "find the former residence known as The Dump" in Atlanta. It referred to the former home of author Margaret Mitchell, but after asking a local for directions Sandy and Jeremy assumed it meant a furniture store, where they spent time running up and down the aisles looking for a clue box.
At The Dump, the roadblock saw finalists having to type out their next clue using a broken typewriter. The key was figuring out a lower case 'L' could be used in place of the missing '1' key. Ernie completed the task quickly for himself and Cindy, easily moving on to the next clue which involved figuring out that the numbers 44-715-74 referred to Hank Aaron's record breaking home run, commemorated on a wall at Turner Field.
Waiting at Turner Field was a giant map which one team member had to scale in order to track their journey across the globe using a piece of rope, the order being: Taiwan, Indonesia, Thailand, Malawi, Denmark, Belgium, Panama and USA.
Cindy took on the task and finished it quickly, heading towards the finish line at Swan House with Ernie before Jeremy & Sandy or Marcus & Amani had even arrived.
Marcus & Amani remained in third place throughout the final leg after struggling to complete the flight simulator challenge, and we never saw them taking on the typewriting or map tasks before they arrived at the finish line.
Speaking after the results, Sandy said the race had "done a lot" for her relationship with Jeremy: "We've learned how to communicate with one another and I think that can take some couples decades. We've learned it in 30 days."
Jeremy agreed that their relationship would "only get stronger" from this point.
Amani added: "I think the big lesson in this is you won't win at everything, but whatever you do, don't quit. Give it your all and go for it. I think making it as far as we did is winning."
The Amazing Race returns for a 20th season next year on CBS.
