The remaining ten teams took off from the Pit Stop at the Connemara Heritage Center in Ireland and were instructed to fly to Amsterdam in the Netherlands, nearly 600 miles away and then search the city's canals for a bridge. As the scramble for flights began, all teams secured an initial flight, but others did not make an early connecting flight. Once in the Netherlands, the teams were faced with Detour options involving either heavy lifting or careful searching. Some teams quickly completed their assigned tasks, while others became frustrated and either switched tasks or lost valuable time as they struggled to stick with the task they had chosen. The teams then traveled by bus to their next task, a Roadblock involving ditch vaulting. As the task required the racers to travel across a muddy pit, some found themselves getting very dirty. Afterwards, both team-members were required to ride in a Dutch cargo bike to the Durgerdam Yacht Club, the leg's Pit Stop. Some teams became last on the way, but ultimately one team was unable to overcome having lagged behind throughout the leg and was eliminated from the race.
The teams take off from the starting line at the Playboy Mansion in Beverly Hills, California and are instructed to fly to Shannon, Ireland. A flight delay leaves teams that thought they were ahead scrambling to catch up. The teams travel to the world's smallest church and then sign up for one of the three ferries departing the next morning. They're then directed to drive 42 miles to Cleggan farm where they must ride a tandem bike to a clue. One member of each team then completes a task that involves more biking -- highwire bicycling while their teammate rides below. Many teams are then frustrated by a task that requires them to fill a basket with fifteen pieces of peat and then transport it using a donkey. Controlling the donkeys proves more difficult for some teams than others and once again some leading teams take a plunge. Ultimately, one team is unable to recover from poor performance on this task and is eliminated from the race.
The All-Stars final three -- Dustin & Kandice, Eric & Danielle, and Charla & Mirna -- compete in the final leg to determine who will win the one-million-dollar prize. The teams take off from their Pit Stop in Guam and are instructed to fly 3,500 miles to Honolulu, Hawaii. One team secures an early flight, but the advantage is largely neutralized when the teams must sign up for charter flights leaving ten minutes apart in Hawaii. The teams travel to Kaumalapau Harbor via Jeeps and find themselves in involved in a Detour that tests their ability at a skill either above or below water. All teams then travel to Shipwreck Beach and crossing rocky terrain, face a challenging kayaking task to retrieve their next clue. Ultimately, all teams board the flight to Oakland, California, en route to their final destination city of San Francisco. A final task tests the ability of the racers to think like their partners. When one team proves rather more adept at it than the others, it turns out to be advantage they need to secure victory. They cross the finish line in San Francisco's Botanical Garden first and become the winners of The Amazing Race: All Stars.
Teams take off from their Pit Stop at the Triho de Taipa Pequena 2000, receiving a clue to fly 7,500 miles to the island of Guam, then drive nine miles to Anderson Air Force Base. A struggle for flights results in one team only narrowly making it onto the first flight to Guam with the other three teams. Once at the Air Force Base, the teams are escorted by naval officers to a control tower, where they receive a clue for a Detour in which they can choose to test their mettle at cleaning, or dare for some high-flying. On the way to the next task at the U.S. Naval Base, one team finds itself lost and needs local help in order to locate the destination. As other teams complete the Roadblock task, they fall behind. Still behind as others are struggling to complete the Roadblock task, a search-and-rescue, they try their best, but fear elimination. In the end, they are ultimately unable to catch up and check in last at the Pit Stop, Fort Soledad, and are eliminated from the race. The final three teams are left to race in the finale for the one million dollar prize.
The four remaining teams set off from the tenth Pit Stop at the Hong Kong Jockey Club and travel forty miles away to Macau, riding on turbojet ferries. The teams are pleased to find that they are able to procure these ferries early in the morning, but less pleased when they find that their next destination, the Macau Tower, does not open until 8 A.M. When one team faces financial difficulties, they make a deal to Yield another team in order to procure much-needed cash. Once the Tower opens, one member of each team takes part in a Roadblock that involves the highest jump in the history of the show. After completing this task, the teams took a taxi to the Lou Lim Ioc Garden, where Detour tasks tested either their ability to pay attention to detail or their mettle at navigation. Upon completing this task, all teams were faced with the challenge of driving a mini-moke. Navigating this unfamiliar vehicle to the Pit Stop proved a major challenge for some teams, and in the end, one checked in last, only to receive a major surprise.
The four remaining teams compete in the tenth leg. At the Pit Stop at the "Mansion on the Hill" in Kuala Lumpur, Malaysia, they receive a clue instructing them to fly approximately 1,500 miles to Hong Kong. Teams find themselves in a struggle for standby flights, with confusion and bitterness regarding line order. Following Dustin and Kandice's choice to use the Yield in the previous leg, the other teams align against them in the hopes of becoming the final three. Once in Hong Kong, the teams travel 22 miles to a laundry. A high-speed fast forward catapults one team to first place, but they find themselves in dire financial straits. The remaining teams all take part in a physically demanding climbing task for the Detour, though one waffles as to which task to choose before making their ultimate decision. This team then makes a critical error when instead of taking the Star Ferry to Hong Kong Island, they instead end up on a completely different ferry to Kowloon. After kicking down doors in the Roadblock and carefully pulling Travelocity gnomes across a pond, the teams head for the Pit Stop, the Hong Kong Jockey Club. The two trailing teams face heavy traffic and navigation confusion and one receives some relieving news upon arriving at the Jockey Club.
The teams are instructed to travel from their Pit Stop at the Pieskowa Skała castle in Krakow, Poland and fly to Kuala Lumpur, Malaysia, over 5,500 miles away. Once there, the teams search for the best way possible to get to the Batu Caves, traveling by both bus and train. A Detour proves frustrating for some teams and even more frustrating for another, who first has to wait out a Yield before making their way to their chosen task. Stress and frustration cause two teams to switch Detour tasks, which one arguing over the specifics of what's required for a particular task. After completing the task, the teams then travel by taxi six miles to Taman Sri Hartamas and locate a newspaper. A Roadblock proves physically tiring for several of the Racers, but assistance from locals and perseverance see them through the task. Ultimately, a missed flight connection dooms one team. Unable to quickly attain alternate travel, they fall far behind and do not arrive in Malaysia until well after the other teams, leading to their elimination.
The teams continue in the second part of a double-length episode. Departing from the Pit Stop nearby the Jan III Sobieski Lozenki statue in Warsaw, Poland, the teams learn that they must travel by charter bus to Auschwitz, Birkenau. The charter buses carry three teams and leave four hours apart. Upon arriving at the Auschwitz concentration camp, teams are required to light a candle and have a moment of silence for the victims of the Holocaust. It's a very emotional moment that teams find themselves reflecting on and in some cases relating to personal experiences, or past history of their own families. Teams then proceed forty miles to a theatre in Krakow where they find themselves facing an Intersection, requiring them to pair up with another team. Two teams work this great advantage by partnering for a Fast Forward, but one loses a sizable lead by being forced to wait for the trailing charter bus. All teams ultimately find themselves heading to the Pieskowa Skała castle. Those that did not claim the Fast Forward must first complete the Roadblock before checking in, but one is too late and is eliminated from the race.
In the first portion of a two-parter, teams left their Pit Stop at the Old Fort in Zanzibar, having received instructions to fly 5,000 miles to Warsaw, Poland and then find the Czapski Palace and a courtyard with a composer dressed as Frédéric Chopin playing the piano. Teams were provided with tickets but were under no obligation to use them, leading to a scramble to find earlier flights. Most teams were successful, but two trailing teams were forced to the provided flight and then missed a connection, placing them far behind. Once in Warsaw, the teams took part in a Detour, with one option requiring precision and skill and other requiring brawn and a bit of luck. Both tasks produced a clue leading teams to Jan III Sobieski Lozenki. Upon finding this monument, teams traveled a short distance to the nearby Pit Stop. The two trailing teams battled it out for last place, and one was pleased to find that they were not eliminated. However, both of these trailing teams arrived at the Pit Stop after others had already left for the next leg. They faced an uphill struggle to remain in the game as events continued in the second part.
Teams take off from the their Pit Stop at Fort Aleza in Maputo, Mozambique and are instructed to fly to Dar Es Salaam, Tanzania, 1,400 miles away. A scramble for flights immediately begins and teams find that flight placement in this leg plays a major role in where they will ultimately end up. One team makes a risky move in opting to take standby-only seats on a flight, which ultimately gains them valuable time and allows them to arrive in first. One team is disappointed when they believe they have secured seats on a flight, but are removed, told that they had been given the seats in error. Once in Mozambique, teams takes one of four dhows (ferries) into Zanzibar, where they then take part in a Roadblock that requires them to choose between either a task that "taxes the mind" or one that "taxes the muscles." They then traveled 15 miles by taxi to the "bush country" of Kikungwi for a Roadblock that involved skill and accuracy. In a leg that involved a great disparity between first and last, a close finish led to the elimination of another team.
