A cancer survivor who can bench press 162 kilograms and run a sub-2:40 marathon isn’t your typical athlete.
But Ivan Vault isn’t typical in any sense of the word.
The 32-year-old Norwegian kayaker, who underwent extensive chemotherapy, has achievements that defy conventional athletic boundaries.
His story reveals how one niche sport might produce more “hybrid athletes” than any other—and why the combination of strength and endurance isn’t as impossible as most people think.

From Professional Kayaking to Cancer Survival
Vault competed as a professional kayaker, earning the title of European champion and collecting four World Championship bronze medals. His specialty was long-distance events, particularly the grueling 5,000-meter and 30-kilometer races that demand both explosive power and relentless endurance.
Kayaking at elite levels requires athletes to maintain maximum heart rate for extended periods. In mass-start events, competitors go all-out from the beginning, building massive lactate levels within minutes.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
With a mass start, you just have to go all out from the beginning like full. So you build up a lot of lactate. Just the first minute like a lot, like let’s say 20 millimoles after a couple minutes, which is a lot. People wouldn’t be able to stand with a 20 millimole level.
Then cancer struck. Vault discovered a cancerous tumor on his thigh and underwent extensive chemotherapy—the same brutal treatment his younger brother had endured just years earlier.
Why Kayakers Might Be Ultimate Hybrid Athletes
According to Vault, kayaking produces more athletes with combined strength and endurance than almost any other sport. The reason is simple: the sport demands both simultaneously.
Elite kayaking sprinters can bench press over 200 kilograms and perform pull-ups with 100 kilograms attached between their legs. Yet even these strength-focused athletes maintain substantial aerobic capacity because water feel and technique require consistent aerobic training.
I promise you it’s kayaking. It is a combination of strength and endurance. That’s what we’re working on.
Vault’s younger brother, also a kayaker, casually beat the world record on the ski erg one Sunday evening—a machine that measures upper-body endurance. The record had been held by one of Norway’s best long-distance skiers.
That same brother also won a national rowing championship on his first attempt, competing against Olympic rowers in their own sport.
Running a 2:39 Marathon After Chemotherapy
Just months after completing chemotherapy, Vault was challenged to run the New York City Marathon as a charity fundraiser. With minimal running-specific training and a recent injury, he finished in 2:44.

Weeks later in Valencia—known for its fast course—he ran 2:39.
I did 2:44 and then I surprised myself. I didn’t expect to be that fast. So a few weeks later, I ran Valencia, which is a fast track, and I did 2:39.
Vault never competed as a runner. His cardiovascular foundation came entirely from kayaking and cross-country skiing—sports that allow much higher training volumes than running without the same injury risk.
The Day Before Chemotherapy: A Record-Breaking Kayak Crossing
After his cancer diagnosis and surgery, doctors informed Vault he would need six months of heavy chemotherapy. The day before beginning treatment, he kayaked 130 kilometers across open ocean from Denmark to Norway, setting a new record.
The day before starting chemo I did the crossing from Denmark to Norway and did the record there. In that moment, you just focus and you just do whatever really inspires you and gets you motivated.
This wasn’t about improving performance metrics. It was about doing something meaningful before facing an uncertain future.
Bench Pressing 162 Kilos Without Being a “Lifter”
Despite never training as a dedicated strength athlete, Vault can bench press 162 kilograms. More impressively, he recently completed 11 repetitions at 130 kilograms during his final set of the day.
His upper-body strength comes from years of resistance training integrated with kayaking. Even during chemotherapy, the bench press became something tangible he could work toward.

I was that that’s what I was saying because I posted this actually on social media, the 11 times 130.
At 85 kilograms bodyweight, Vault can perform three sets of 30 pull-ups. At age 13, he completed 205 push-ups in a single set during a school fitness test.
Training Philosophy: Volume Over Intensity Post-Cancer
Vault’s current training looks dramatically different from his pre-cancer regimen. During peak competition years, he completed three to four training sessions daily on training camps, focusing entirely on eating, sleeping, and training.
Now, with a full-time job as a power systems engineer and side businesses, his training volume has decreased substantially. He lifts weights one to two times weekly and runs 50-60 kilometers per week when preparing for running events.
He’s also learned to reduce intensity as he ages.
When I was younger, I would put in much higher intensity, but I feel I can’t do that anymore. I will just be slower.
Cross-Country Skiing and Ski Erg: Secret Weapons for Endurance
According to Vault, cross-country skiing might be superior to running for building systemic cardiovascular capacity. The reason: volume.
Elite runners can’t match the training hours of cyclists, rowers, or skiers due to running’s high impact. Cross-country skiing provides exceptional aerobic development while engaging both upper and lower body musculature.

To just build like full systemic fitness as a cardio exercise, I wouldn’t probably say that running is the best option. It’s really hard impact but a combination, you know, a combination of a lot of things.
Norwegian athletes use cross-country skiing extensively for winter base building. The ski erg machine—which mimics the double-poling motion—offers similar benefits and is accessible year-round.
The Vault Family: Genetic Freaks or Products of Environment?
Ivan isn’t the only athletic anomaly in his family. His older brother held the course record for the Norseman—widely considered the world’s toughest Ironman distance triathlon—for six to seven years.
His younger brother, also a kayaker, won the World Cup twice in one season while Ivan finished second both times. Then, just two weeks before Olympic qualifiers, the younger Vault was diagnosed with leukemia.
After two and a half years of chemotherapy and a bone marrow transplant from the older brother, the youngest Vault returned to competition. One year after his bone marrow transplant, he finished one second away from qualifying for the Olympics, losing to an athlete who went on to win Olympic silver.
We were one second from winning but we missed it and the guy won and got the silver in the Olympics, one year after his crazy treatment.
Building Both Strength and Endurance: Lessons From Elite Kayaking
Most athletes must choose a lane—endurance or strength—because the training demands conflict. But Vault’s experience suggests there’s more overlap potential than commonly believed.
Even Olympic decathlon champion Marcus Rut acknowledged the tradeoff, noting his 1,500-meter performance suffered because he benched 160 kilograms.

He would be able to run a good 1,500 meter if he didn’t push 160 in the bench. Even one of the most versatile athletes in the world is saying exactly that.
Yet Vault—who can run faster than Rut in the 1,500 meters and bench more—demonstrates that with the right sport background and training approach, exceptional hybrid athleticism is possible.
Key Principles for Hybrid Training
- Prioritize low-impact endurance work like cycling, rowing, or skiing that allows high volume without injury
- Integrate resistance training consistently—one to two weekly sessions maintain significant strength
- Focus on pull-based upper body work for balanced development and injury prevention
- Reduce intensity with age while maintaining consistency and volume
- Choose sports that naturally combine demands rather than trying to optimize contradictory training stimuli
The Psychology of Performance After Trauma
Vault admits returning to kayaking after cancer hasn’t been easy. Performance regression is difficult for any athlete, especially one who competed at world championship levels.
Running provided a fresh challenge where progression felt more achievable. Setting a marathon PR feels different than trying to return to previous kayaking speeds.
It’s not as fun going back to a sport where you know you’re at a lower level. I took up a little bit of running because I still could make some progression there.
Even during chemotherapy, Vault couldn’t stay away from competition. The drive to race, to test himself, remained constant despite feeling physically depleted.
His story illustrates something crucial: athletic identity runs deeper than physical capacity. When facing mortality, the instinct isn’t to rest—it’s to prove you’re still alive by doing what makes you feel most human.
What Makes Norwegian Athletes Different?
Vault jokes that Norwegians shouldn’t be allowed to compete in hybrid athletic challenges because the standards might be too easy for them. While said with humor, there’s truth beneath it.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Norway’s culture emphasizes outdoor activity, particularly cross-country skiing, from childhood. This builds exceptional aerobic foundations that transfer to virtually any endurance sport.
Cultural humility also plays a role. Vault’s colleagues at his engineering job have no idea about his athletic achievements. Norwegian culture discourages bragging—there’s even a concept called “Janteloven” that suggests you shouldn’t think you’re better than anyone else.
I don’t think my colleagues are aware of what I’m up to. I’m a power system engineer.
Imagine having Wolverine working at the desk next to you and never knowing.
The Untapped Athlete Challenge
Vault discovered the Untapped Athlete Challenge—which seeks athletes who can both run a sub-2:50 marathon and bench press 110 kilograms for 10 repetitions—through social media. His response to the initial parameters: “rookie numbers.”
He’s right. With a 2:39 marathon and the ability to bench 130 kilograms for 11 repetitions, Vault exceeds the challenge requirements by considerable margins.
Both his brothers likely could complete the challenge as well. His younger brother has the strength but might struggle with running speed due to his size. His older brother, the Norseman record holder, would crush the running requirement and could train to the bench press standard.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
What’s remarkable isn’t just that Vault can do both—it’s that he can do both after cancer and extensive chemotherapy, while working a full-time job, without dedicating himself entirely to training.
Sleep, ADHD, and Performance
Despite his achievements, Vault struggles with sleep—a significant weakness he acknowledges. Diagnosed with ADHD as a child, sleep difficulties have plagued him throughout his athletic career.
When I was really trying to become the best in the world as a kayaker, it was something I struggled a lot. It’s probably one of my weaknesses.
The ADHD also brings benefits: intense focus on interests and the ability to become completely absorbed in pursuits. This hyperfocus likely contributed to his success in kayaking and his ability to push through cancer treatment while setting athletic records.
Both his brothers sleep much better, suggesting that even within a genetically gifted family, individual variations exist that affect athletic potential.
The Real Lesson: Hybrid Athleticism Through Sport Selection
Most athletes trying to build both strength and endurance approach it backward. They try to add running to lifting programs or weights to running programs, creating conflicting training stimuli.
Vault’s path suggests a different approach: choose activities that naturally require both.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Kayaking, rowing, cross-country skiing—these sports don’t separate strength and endurance into different training buckets. They integrate both within every session, creating athletes who don’t have to choose between being fast or strong.
For those without access to kayaks or Nordic skiing trails, the principles still apply:
- Emphasize low-impact cardio that permits high training volumes
- Choose full-body movements rather than isolated exercises
- Maintain consistent strength work even during endurance-focused periods
- Build aerobic base through long, slow efforts before adding intensity
- Accept that peak performance in either domain requires sacrifice in the other—but exceptional competence in both remains achievable
Ivan Vault isn’t superhuman. He’s the product of a sport that demanded he become strong and fast, a culture that normalized outdoor endurance activities, and a mindset forged through watching his brother nearly die and then facing his own mortality.
His message is simple: the limits we accept are often smaller than the limits that actually exist.
