Plot

The race

The series opens on race day, September 2019, with Bear Grylls sending 66 teams off from a tributary on the Fijian coast. The first stage is brutal by design: roughly 65 kilometers of rowing from the river mouth into the open ocean, out to the island of Ovalau, where each team must dive about 15 feet down to retrieve the first of five medallions. Grylls swan-dives backwards off a boat to demonstrate the dive. Some teams row the entire way; others raise sails and rest their arms for what is coming.

The race barely starts before it starts breaking people. A team from Bend, Oregon, led by Jason Magness, holds pole position through the first day until one of their four is overcome by heatstroke and has to be carried through the course. Less than 24 hours in, a front-runner is being literally dragged along by his teammates as the team slides from first to 57th. Spain's Team Summit is diagnosed with hypothermia. An Irish competitor develops trench foot so severe he cannot walk unaided for a fortnight afterward. The course does not care who you were on land.

The show's heart, though, is not the leaders. It is Team Endure: Mark Macy, who has raced in every Eco-Challenge the producers have staged over 25 years, now diagnosed with early onset Alzheimer's, racing alongside his son Travis. Travis gave up a spot on an elite team to race with his father, knowing this is the last chance they will ever get. Mark's diminishing cognitive capacity makes simply completing the course remarkable, and the camera follows every stumble and every moment his son steers him straight.

The storm in the canyon is the sequence everyone remembers. A tropical storm slams into the course while Team Estonia is descending into a canyon, and the race director halts the entire contest for hours as the team clings to the rock in rising water. The footage, shot by a cameraman identified only as Pablo, is extraordinary: headlamps in the dark, ropes slick with rain, racers hauling each other out of a gorge that has turned into a drain. It is the moment the series stops being a competition show and becomes something closer to a survival documentary, and it is the sequence the producers themselves point to as the best thing they captured.

As the days grind on, the field stretches out. Team Onyx, the first African-American endurance team in Eco-Challenge history, races to inspire younger Black athletes; their founding member says so plainly and the show lets him. Team Unbroken includes a legally deaf female war veteran. Team Stray Dogs, a group of men all in their 60s, keep plodding while younger teams drop out. Two teams have to be pulled off the course by helicopter rescue, and in the final stretch a team must be rescued from the open waters of the Pacific in the middle of the night.

The ending is anticlimactic by the nature of the sport. Team New Zealand, captained by Nathan Fa'avae, the strongest team on the course from early on, reaches the finish line first and is crowned champion, followed closely by the second- and third-place teams. Because the leaders are so far ahead of the stragglers, the winner crosses with two episodes still to air, and the last episodes belong to the back of the field: the teams racing not for the prize but simply to finish, including Team Endure. At the closing ceremony, executive producer Lise Hennessy gives Team Endure the Spirit of Eco-Challenge Award for embodying teamwork, grit, family, and perseverance, the emotional climax the series has been building toward since the first day of rowing. Forty-four teams finish. Grylls had warned before the start that there was a possibility no one would.

Characters

Bear Grylls hosts, narrates, and occasionally shows off, most famously with his backwards swan dive into the first medallion site. Critics found him a bit much but conceded he keeps the stakes visible.
Mark Macy (Team Endure) is the soul of the series, a 25-year Eco-Challenge veteran racing his final race with early onset Alzheimer's.
Travis Macy (Team Endure) gave up an elite team slot to race with his father and quietly carries the team's emotional weight.
Nathan Fa'avae (Team New Zealand) captains the dominant team, steady and ruthless, and takes the crown.
Jason Magness (Team Bend Racing) leads the Oregon squad whose heatstroke collapse early on becomes the series' first great heartbreak.
Tashi Malik (Team Khukuri Warriors) captains one of the international field's most determined underdog squads.

Interpretations and controversies

Critics saw the race format itself as the show's structural problem. Because the field spreads out over eleven days, a winner is crowned with several episodes to go, which The Hollywood Reporter called a formula flaw and Decider called "a damp squib of a finale." Decider also noted that more than half of the 66 teams received no screen time at all, and only about a dozen got more than a minute.

Sequels, spin-offs, and adaptations

The series revives Eco-Challenge, the expedition race Mark Burnett created in 1995 and ran until 2002, with a final edition in 2006; it inspired his reality hit Survivor. No second season had been announced as of the show's release.

The race and its rules

The competition filmed in September 2019, mostly on the Fijian island of Viti Levu, with the course mapped by race designers Scott Flavelle and Kevin Hodder, both veterans of earlier Eco-Challenge events.²^•⁷ The course ran through seven Fijian provinces and crossed the borders of more than 100 villages.⁸

Team integrity is the core rule. Each team of four must include at least one member of each gender, and if any racer quits or becomes unable to continue, the entire team is disqualified. Teams race around the clock with little sleep, navigating by map and compass, and are supported by a fifth member, an assistant crew member who resupplies them at checkpoints.²^•³ The 2019 course was divided into 5 legs with 31 checkpoints.³

The race includes cutoff times that eliminate teams falling too far behind. A Day 3 cutoff loomed in the early episodes, and a tropical storm forced organizers to stop the race entirely; episode three, titled "This Race Is Back On," covers the resumption after the weather break.⁹ Teams that could not continue were pulled from the course by helicopter rescue.⁹

Outcome

Team New Zealand, captained by veteran adventure racer Nathan Fa'avae, finished first and won the $100,000 prize. The runner-up spot, along with $50,000, went to Team Canada Adventure, while Australia's Team Gippsland Adventure claimed third place and $25,000. In all, 44 of the 66 teams finished the course; Team Eagle Scouts placed 43rd, completing the journey 90 minutes before the course closed.⁴ The frontrunners finished in under six days, well inside the 11-day limit.¹⁰

The field mixed elite and amateur teams. Among them was Team Onyx, the first all-Black team to compete in Eco-Challenge, whose captain Clifton Lyles said he wanted to diversify the sport and serve as a role model.⁷ Team Endure featured Mark Macy, who had raced the 2002 Fiji Eco-Challenge, competing alongside his son Travis after an early-onset Alzheimer's diagnosis ended his plan to reunite his old team.⁷ Team Khukuri Warriors was the first team from India to enter the Eco-Challenge.¹¹

Origins of the franchise

Eco-Challenge was created by Mark Burnett, now chairman of MGM Worldwide Television, who drew inspiration from New Zealand's Southern Traverse and the Raid Gauloises adventure race. The first 11-day race began in April 1995 in southeastern Utah, and subsequent editions were held in Australia, Morocco, Patagonia, Borneo, Canada, and New Zealand. The last televised competition before the revival took place in 2002, also in Fiji, in the series' seventh season.² Burnett chose Fiji again for the reboot, citing his experience there and the country's film and television capability.⁸

Producers Mark Burnett and Lisa Hennessy decided in the summer of 2018 to revive the franchise, and the resulting production cost tens of millions of dollars.¹² Burnett had earlier created Survivor, and the series is frequently described as coming "from the creator of Survivor."¹³

Production scale

The revival was a substantially larger undertaking than its predecessors. The production employed roughly 1,000 people, and 41 camera crews captured the action across the course.²^•⁶ Amazon required delivery in 4K HDR, which led the camera team to test a shortlist of eight camera systems in the Florida wilderness to simulate Fiji's tropical conditions before recruiting more than forty cinematographers and operators.¹⁴ Producers also secured permission from village chiefs along the route, holding kava ceremonies before filming in each community.⁷

Reception

Critics responded positively. The season holds a 90% Tomatometer from 10 reviews on Rotten Tomatoes, against a 47% audience score.⁵ TV Guide Magazine called the show "life-affirming," and The Hollywood Reporter praised its consistently stunning visuals while noting that the race's structure limited the production in other ways.¹⁵ Reviewers singled out the cinematography and the human stories of the slower teams, while some criticized Bear Grylls' narration as expository and noted that the frontrunners finishing by episode eight drained competitive tension from the finale.⁷^•¹⁰ The series received one Directors Guild of America nomination.¹⁵

No second season followed. The return of the race after a 17-year hiatus was credited in the adventure racing community with re-energizing the sport.¹⁶
