Seven Marathons, Seven Continents: Michelle Khare's Opening Days of the Great World Race

Open on YouTube ↗
Overview

Michelle Khare opens the episode by saying that, after years of extreme challenges on the channel, this is the first one they genuinely believe might be impossible. The Great World Race asks runners to complete seven marathons in seven days on all seven continents, living aboard a chartered plane between stops. According to the video, fewer than 300 people have ever finished all seven. Khare's central question is whether they can do it, and what kind of person they would be on the other side if they did. This first episode covers the seven months of preparation, a last-minute schedule change, and the first two races: Cape Town, then Antarctica.

The Route and Why It Is So Punishing

The race was planned to start at the bottom of the globe with a marathon at Wolf's Fang, Antarctica. Runners then fly to Cape Town, South Africa; 12 hours to Perth, Australia; another 12 hours to Abu Dhabi; on to the coast of Portugal; seven more hours to Cartagena, Colombia; and finally a few hours to Miami for the finale. The seven races span five very different biomes. Antarctica is the coldest stop, and Khare learns during training that every remaining race will be run in extreme heat. News clips in the video mention Western Australia's driest month on record and record-breaking temperatures in the UAE.

David Kilgore, a professional Red Bull athlete who is running the event for the third time and says plainly that they intend to win it, calls Antarctica the most challenging race and the most challenging continent. Kilgore also points out that it is normally the first marathon, so it sets the tone, and there is a real chance that people, Khare included, will not finish it.

Lab Testing: "A Well-Tuned Audi, Not a Ferrari"

Preparation began at a high-performance lab where Khare was tested in front of coach Gareth Thomas and Kilgore. Khare admits to feeling intimidated: being tested by someone who tests world-class athletes, in front of a world-class athlete and a world-class coach. Thomas says that when they first heard about the Great World Race, they thought it was crazy, even after a lifetime around Ironman races and the Tour de France.

The lab staff explain what an endurance event demands: the runner has to be very efficient at burning fat. A mask worn during the VO2 test shows how much fat and carbohydrate is burned at different intensities, and blood lactate measurements show how effective the athlete is metabolically. One of Khare's readings came in at 13.2. The tester called it high and said it reflected good anaerobic capacity. Khare's VO2 max was 48 ml per minute per kilo, which the tester placed a little below average for runners. The tester's verdict was that Khare is "a well-tuned Audi, you're not a Ferrari," which is better than being "a poorly tuned Ford Focus."

Thomas turned the data into a seven-month training plan built around Khare's body, ability, and this specific event. Khare summarizes it as "a lot of running." On the training calendar, black marks shorter runs of 1 to 9 miles and blue marks runs of 10 miles and up, such as an 18-mile day. Repeat lactate and VO2 max tests are scheduled throughout to update the data. The lab staff's stated goal is that every workout has a purpose grounded in these markers.

Rehearsing Antarctica in a Freezer and the Heat in a Chamber

To simulate Antarctica, the team trained in a cold storage freezer at 5°F (-11°C). The purpose was to mix and match gear and find what would work on race day. The hardest problem was keeping gels and water from freezing. An insulated bottle helped, but eating a gel with gloves on was another obstacle. Khare joked that Thomas would have to feed them.

Thomas explains the choice of fuel. Energy gel is essentially concentrated carbohydrate, and the ones that work best scientifically taste bland. The team chose products that worked and didn't cause stomach distress over ones with good flavor. Their freezer solution was to keep the gels next to Khare's body, and the gels stayed unfrozen.

Psychologically, Khare says the session was hard. They felt strong impostor syndrome, as though everyone else had far more experience. Kilgore replied that everybody feels that way, "even me." Kilgore's approach is to enjoy the moment, especially somewhere as wild as Antarctica: to look around and think how insane it is to be there. Kilgore also told Khare they were already winning by putting themselves out there. Khare returns to this advice at the end of the episode.

Heat preparation took place in a hot, humid chamber. A sensor fed exact sodium and water loss to Khare's watch, and Thomas monitored a heat-stress gauge. The lesson Khare takes from it is that in hot environments, they need to run intentionally slower.

A Training Year That "Felt Like Being Thrown Into a Blender"

Khare says plainly that the ideal training scenario fell apart. Halfway through the program, a lactate test showed extreme fatigue. Thomas said that as soon as they saw two particular data points, they knew Khare was fatigued.

Khare explains that these challenges are never done in a vacuum. Khare describes taking a red-eye to France, running 10 miles right off the plane, and then going to film Jet Lag: The Game. Another day started at 4:15 a.m. in Vienna, with a couple of hours of running before a shoot. Khare had originally hoped all the travel would be good preparation for a race spent on a plane. Instead, by Khare's account, the travel compounded the fatigue "to a massive degree." Then Khare got COVID, spent three weeks in bed, and lost an entire month of training. Rather than watching their Strava numbers steadily improve, Khare describes the year as a roller coaster "where the car flew off the tracks and we landed in the pond near Six Flags."

During this stretch, a friend offered a reframe. Their little sister watches Khare's videos and looks up to them, as do millions of other people. Every ounce of effort and pain, the friend said, becomes a moment of inspiration for those people.

Going Public and Facing Doubt

Khare usually keeps a challenge private until it is finished. This time Khare posted about it online beforehand, and many people responded that Khare shouldn't or couldn't do it. In person, some reactions were simply alarmed, along the lines of "Oh my god, Michelle. How? Why?" Khare hopes those sentiments came from care, but says they weren't what Khare needed to hear. Khare admits wanting the willpower to say "I'm going to prove them wrong," but also wondering, "what if they're right?"

The doubt carried into the race briefing. Khare compares it to walking into a high school reunion for a school they never attended. Everyone else seemed to know each other and could trade stories about major marathons and world records. Among the other runners was Jacky, a South African runner whose leg was amputated within three weeks of a bone cancer diagnosis at age 26, and who has run 104 marathons in a row. Khare joked that this event must be a warm-up for Jacky, but says that meeting such accomplished people made them doubt themselves further.

The Briefing: Antarctica Is "Designed to Kill You"

The organizers described these as events of uncertainty, which they called part of the adventure. They said Antarctica's weather can go from clear skies one day to a blizzard the next, and that conditions can turn bad enough to strand people there for days. They listed blue ice that can break a leg, crevasses, disorienting darkness and brightness, and the risk of getting lost. One speaker summed it up: "Everything there is, yeah, designed to kill you. People aren't supposed to be there." The organizers also warned that the thin ozone layer makes UV intense, and with the glare off the snow, snow blindness is a real danger. Runners would wear glacier glasses. Runners were firmly told not to leave the area where the teams were stationed, even to relieve themselves. Khare saw fear on many faces in the room.

14:39

Chaos Before the Start: Antarctica Moves to Second

Before the race began, the organizers announced that changing weather at Wolf's Fang meant Cape Town would be run first. Khare explains why this matters: the race historically starts in Antarctica because, in theory, you want to race it on your freshest legs. Now the runners would complete a full marathon in Cape Town and then run Antarctica within the same 24-hour window. Khare called a last-minute crew meeting to revise the whole plan. Khare had never run two marathons back to back. After every previous marathon, Khare says, they went home, ate ice cream, and lay down for hours.

15:54

Marathon One: Cape Town

On race morning, Kilgore advised starting slower than feels natural, because the day would heat up toward the end. Khare was surprised to find members of the Challenge Accepted community at the start. One of them, Phoebe, had baked something at midnight. Having trained mostly alone, Khare says this gave them a huge energy boost.

The course was six 7K loops with two aid stations, which Thomas says made fueling easy. Each time Khare passed the start, they took a particular waffle they liked. Khare also carried a bottle of water with sodium, so hydration was covered continuously. Thomas's master plan assumed each loop would take about 40 minutes, with adjustments as the race went on.

Khare found this very different from a big city marathon, where thousands of runners share your pace. Here Khare was often alone. Khare's strategy was to find a running buddy as quickly as possible, someone whose energy could pull them along. Khare ran stretches with Jamie and Silviu, but these partnerships kept breaking up as people sped up or slowed down. Few runners were at Khare's pace. Khare's goal for the week was to finish each marathon in five hours or less.

Kilgore offers a sense of scale. Most people starting out in marathons aim for under four hours, and a sub-three is the "diamond standard." Kilgore's personal best is around 2:27 and they ran Cape Town in 2:58, which Kilgore jokingly called their best Cape Town marathon ever, since it was the first one of the year. Kilgore says the overall volume of this year's race was more nerve-wracking, and that uncertainty is a big part of the event.

Khare had run only two marathons before this: the LA Marathon and an ultra in Death Valley. In both, Khare felt they had barely scraped by because they hit the wall. Thomas rejects the concept. The wall is the idea that around mile 20 an energy block stops you, and Thomas calls it "mathematically nonsense," because people run 100-mile races and these runners would complete seven marathons in a week. In Thomas's view, hitting the wall just means running too fast and not fueling correctly. Thomas describes Khare as a high-carb burner and says they had no worries about Khare hitting the wall, because the fueling plan was based on science and Khare's own physiology. Late in the race, Khare reported that the plan seemed to be working, even though their pace was slow.

Khare finished in under five hours, the goal they had set. Thomas was proud but flagged the concerns ahead: a quick turnaround, getting enough hydration in, and a hard recovery. Khare also noted that while the community's support had carried them, they couldn't depend on it going forward, because "ain't nobody coming to Antarctica."

22:16

Marathon Two: Antarctica on Tired Legs

On the flight south, Khare was amazed at how chipper the other runners seemed, as though they hadn't just run a marathon. Khare felt their own fatigue was obvious. Kilgore explains that every race has a time limit, and Antarctica's is the harshest: the plane is on the ground for only eight hours, so the entire marathon must be finished within that window.

The landing on an ice runway felt chaotic. Khare worried about where their gear was, whether they had eaten enough, and whether they had packed enough clothing compared with everyone else. Under a perpetual sunset, it was -12°C at the start. Khare joked that this was warmer than the freezer. The course was 10 laps. Thomas's instructions were to start slow, take whatever fuel was available, and focus on breathing.

Thomas stresses that this wasn't really "day two." It was a marathon starting about 14 hours after the previous one, on ice, in cold and wind, with difficult footing and a heavy mental load. Khare's fleece froze. The body-heat method for gels worked, and Thomas handed gels to Khare between laps. Thomas said Khare was slower than in Cape Town but had to be more careful in the conditions.

29:24

Running With Tariq

Khare found a partner in Tariq Amassyali, runner number 62, who was running the Great World Race for the second year in a row while wearing a tuxedo. Tariq jokes that they hadn't known who Khare was until their daughter Lex mentioned it, and Tariq's response was that since Tariq had done the race before, Khare was the one running with Tariq. The two worked as a team. One would run in front to block the wind for a lap, then they would switch.

When Khare asked how to get through something like this, Tariq said the purpose has to be bigger than the pain. Tariq's purpose was men's mental health. Tariq cited a statistic that a man dies by suicide about every 60 seconds. Tariq explained that the tuxedo represents a facade: when you see someone who seems to have everything together, you have no idea what they're going through mentally or emotionally. Tariq's philosophy is that if wearing a tux for seven marathons changes even one person's life, the effort is worth it. Khare's answer was simpler: they saw the race, doubted they could do it, and decided to try.

Their plan was to warm up at each aid station, but every minute spent warming up was a minute less to beat the cutoff. By lap four, they reported winds of about 25 knots and a temperature of -23°C. To pass the time, Khare asked Tariq about their favorite place in Miami. Tariq warned it would bring tears, and Khare replied that the tears would freeze to their face. Tariq says Khare was intensely focused on finishing before the cutoff, since the plane would leave at the eight-hour mark no matter what.

33:23

The Front of the Field

Kilgore finished in 3:55, more than an hour slower than the previous year, which Kilgore offers as evidence of how brutal the conditions were. Kilgore joked that their tongue started freezing to the medal, and said it was a privilege to go through that brutality in such a place. When asked whether they'd had deep conversations on the course, Kilgore said only with God, and God said, "You're in hell." Watching Khare stop to warm up and then head back out, Kilgore says that was the moment they became convinced Khare was tough and would get through the event.

35:14

Leaving a Partner Behind

As the race went on, Khare slowed down and grew emotional, and Tariq hit a rough patch. Vehicles began picking up runners who weren't moving fast enough and taking them to the plane by sled. Khare says fear set in at that point. Khare was walking a lot, and had abandoned any target pace, time, or heart rate. Khare faced a decision: wait for Tariq, or keep going. Khare reasoned that waiting would mean cooling down and starting to freeze, which could cost them the finish. The team's goal was to cross all seven finish lines, so Khare went on alone.

On the course, Khare cried and said it felt like everyone else could do this except them. Thomas reassured Khare that they would finish, and in a really good time, then left Khare to complete the final stretch. Khare describes it as haunting. No one else was in sight, their watch had died, their shoes kept slipping, and they weren't even sure they were on course. Khare thought Tariq was somewhere behind but couldn't check, because stopping risked being picked up and left behind. Khare says that when people ask about the hardest challenge they've ever done, there is now a clear answer: this day.

What kept Khare moving was Kilgore's earlier advice to pause and take it all in. Few people ever get to experience Antarctica, a place Khare describes as untouched, raw, and brutal, and Khare told themselves over and over that they would probably never be there again. Khare says that by then, this thought was all they had left.

38:44

The Finish and No Time to Celebrate

Khare crossed the finish line in tears, repeating "It's done," and saying this had been the hard one. A crowd of fellow runners congratulated Khare. But one second after finishing, Khare was told to grab their things and board the plane. There was no time to change clothes, use the bathroom, or eat any of the catering Khare had watched others enjoy for the past three hours.

The episode ends with two of seven marathons done and a preview of what's next. Runners compare the plane to a party in the sky. Someone asks whether any race will be harder than Antarctica, and runners say they are bracing for the heat. Clips show the heat at its peak, terror on runners' faces, and Khare saying the inside of their knee hurts so badly they can't run. The preview also introduces Dan Little, 83, who is running the Great World Race for the fourth time. Whether Khare can finish the remaining five races is left for the next episodes.
