In the mornings, Alexander Rončević taught first-graders at an elementary school in Vienna. In the afternoons, he trained. In the evenings, he coached swimming.

Somewhere in between, he became the best HYROX athlete in the world.

For years, he balanced all three. In fact, until early 2025, just months before rewriting the HYROX record books, Rončević was still teaching full-time while training to compete against the fittest athletes on the planet.

For anyone who's ever looked at a packed schedule and thought, I'll train tomorrow, his story is worth paying attention to.

He entered his first HYROX race in 2018 with almost no specific preparation. "Initially, he didn't even know how to perform a wall ball or push a sled," his coach Tiago Lousa recalls. He simply showed up, competed, and learned.

By 2024, Austrian Alexander Rončević was HYROX World Champion in Nice, France crossing the line in 56:21. By 2025, he had won another world title in Chicago and lowered the world record to 53:31, cementing himself as one of the greatest HYROX athletes the sport has ever seen.

In early 2025, he finally made the leap and left teaching to pursue HYROX full-time. The decision reflected something that had been obvious for years. His success was never built on perfect circumstances. It was built on consistency.

Four habits, in particular, helped shape the athlete he became. Let's break them down.

Secret 1: The swimming foundation — it didn't transfer physically. It transferred mentally.

Rončević was a competitive swimmer before HYROX existed as a sport. Hours in the pool as a child. Two-hour sessions before school, then back in the evening.

"Swimming short distances doesn't provide much physical or physiological transfer to HYROX," his coach Lousa explains, "but he developed qualities such as discipline, resilience, endurance, and competitiveness."

That's an important distinction. The swimming didn't make him faster. The swimming made him the kind of person who shows up, puts his head down, and does the work regardless of whether it feels good.

When he switched from swimming to running at around age 22, he started from almost nothing aerobically. "At the beginning 20km per week was enough to improve. Over the years I added more kilometres every week, and now I'm at around 60km."

The discipline to make that progression, quietly and consistently over a decade, came directly from the pool. So did the mental fortitude to continue doing the work even when it didn't feel good.

The closest transferable training tool to the swimming background Rončević credits for his discipline is a Concept2 RowErg.

Like swimming, rowing trains nearly every major muscle group while building aerobic capacity with minimal impact on the joints, allowing you to accumulate a large volume of high-quality conditioning without the pounding of extra running.

Research consistently identifies VO₂max and peak power output on the rowing ergometer as two of the strongest predictors of rowing performance, making it one of the most efficient tools for building a powerful aerobic engine.

Better yet, rowing is also one of the eight official HYROX race stations, so every session improves both your fitness and your race-day technique.

For those without space for a full rower, a speed jump rope is one of the highest-return conditioning tools you can own. Just 10 to 15 minutes develops coordination, foot speed, lower-leg stiffness, and cardiovascular endurance while placing very little stress on your joints.

Those quick, rhythmic ground contacts help reinforce the reactive qualities needed for efficient running and faster transitions between HYROX stations.

It's no coincidence that jump rope remains a staple in the training of elite endurance athletes, CrossFit competitors, and combat sports athletes alike.

Secret 2: The running volume — 20km a week became 60km over ten years

Rončević is not primarily a runner, which is remarkable given that HYROX consists of 8km of running split across the race.

He came from a pool, not a track. Thus, running was something he had to build.

Rončević built it the slow way. Starting at 20km a week at age 22 and adding kilometres year after year, reaching around 60km a week now. For the 2024/25 season, he ran four to five sessions per week, including short intervals up to 400 metres, long intervals up to 2km, and tempo runs of 10-12km at slightly above race pace.

His coach Lousa works with a separate Olympic-level running coach, Wilhelm Lilge, specifically to develop Rončević's running. "His running-specific workouts are designed by Olympic and elite-level coach Wilhelm Lilge. After the last World Championships — where it was the first time in eight years that Alex didn't stand on the podium — Coach Willy and I agreed it was time to slightly re-organize Alex's training."

He also went to Kenya. During preparations for the 2025 World Championships, Rončević skipped the Las Vegas major event to spend 10 days training in Kenya and "run with the best."

Like many elite endurance athletes before him, Rončević traveled to Kenya to immerse himself in one of the world's greatest running cultures. Four-time Olympic gold medalist and six-time world champion distance runner Mo Farah famously spent extended periods training in Kenya throughout his career, crediting the environment, training groups, and culture for helping shape his success.

A week in Kenya gave Rončević a glimpse of what was possible, and the nation left a mark on him. His long-term plans involves going back someday.

The practical lesson for anyone building a running base for HYROX is that the volume doesn't need to be high immediately. It needs to be consistent and progressive. "There is still plenty of room to do more and get better," Rončević says of his own 60km weeks. A man with the world record talks about his running like a beginner still finding the ceiling.

Good footwear matters when you're stacking kilometres. HYROX isn't just an 8 km run. It's eight runs broken up by sled pushes, lunges, rowing, burpees, and carries, which means your shoes need to balance speed, grip, stability, and cushioning. That's exactly why independent lab testers at RunRepeat evaluate HYROX shoes using more than 30 objective measurements, including outsole traction, energy return, stack height, stability, flexibility, and weight.

Saucony Endorphin Pro 5 is ranked as the best Overall HYROX Shoe. Widely praised for its combination of lightweight cushioning, exceptional energy return, stable platform, and smooth forward propulsion.

Rather than choosing a shoe that's only good for running or only good for lifting, it strikes the balance HYROX demands, helping you move efficiently through both the running segments and the functional stations. If you're investing in one piece of equipment that you'll use on every single training session, your shoes are arguably the highest-return purchase you'll make.

A Garmin GPS running watch gives you the data needed to train with the same level of consistency that helped Rončević build himself into a HYROX champion.

His progression from 20 km per week to around 60 km per week wasn't built through random bursts of motivation. It came from slowly increasing volume, tracking progress, and allowing his body to adapt over time.

A quality GPS watch helps you follow that same principle by accurately measuring pace, weekly mileage, heart rate, training load, and recovery between hard sessions.

When improvements are built over hundreds of workouts, knowing exactly what you did and how your body responded is the difference between training harder and training smarter.

Secret 3: Train for fatigue, not freshness

This is the one that separates HYROX training from standard gym programming.

HYROX is not a test of how strong or how fast you are when fresh. It's a test of how well you perform each station when you're already 3km into the run and your legs are cooked. The sled push on a fresh set of legs feels very different from the sled push after two intervals at pace.

Rončević's sessions are structured to replicate this. "These workouts often follow an EMOM (every minute on the minute) style or a work/rest format, incorporating specific paces and tasks designed to align with our goals for an optimal race performance."

Coach Lousa explains that knowing exact outputs matters: "This requires us knowing exactly how many meters Alex can perform in burpee broad jumps or walking lunges in a minute while fatigued, or how many wallballs, or his optimal ski or row pace."

The phrase Rončević uses to frame this is simple.

"Everything you do in the race, you've already done in training."

— Alexander Rončević

Before a race, the mental prep and visulaization is imperative:

"Before a race, I'm thinking about the course. Where are the stations? How does the venue look? You need to be able to adapt to different situations."

— Alexander Rončević

His coach describes the mental edge this builds: "If he's feeling pain and struggling, then everyone else must be in a worse position and will eventually back down before he does."

The home tool that most directly replicates compromised HYROX training is a 20lb wall ball. Wall balls are one of the final stations in a HYROX race, which means you're throwing a heavy ball overhead after already running several kilometres and grinding through seven other stations. Practicing wall balls when you're already tired, at the end of a run rather than at the start of a session, is the single best way to prepare for that specific demand.

Secret 4: The recovery basics nobody follows

Rončević's recovery protocol is not complicated. That's the point.

"If I have another race, I jump on a bike for 30 minutes, just to keep the blood circulating. That flushes out lactic acid and helps prevent stiffness," he says. The rest is built on three things: sleep, hydration, and real food. "Make sure you sleep well. As most people don't even sleep properly."

And the one area he singles out as the most neglected:

"That's where most people have issues and also in their lower back and spine. Mobility makes life way easier and it makes you better as an athlete."

— Alexander Rončević

His coach frames the broader philosophy:

"Be focused, fight for your goals, but not at all costs. Obsession is not a good thing. Alex understands that all his success comes from being happy and in a positive flow state, supported by his family and friends."

— Coach Tiago Lousa

That balance, the same one that let him teach children in the morning and train for a world championship in the afternoon, is part of why he's stayed at the top of the sport for years rather than burning out in one season.

"The willingness to learn continually, the ability to recognize flaws, and the readiness to embrace challenges," Lousa adds. "Don't let your ego stop you from being pushed, from learning. That is where the most growth comes from."

For the mobility work Rončević specifically prioritizes, a lacrosse ball mobility set. Which aides him in lower back and hip tissue work that foam rollers can't reach and hone into with the same pressure.

It is one of the simplest tools for targeted tissue work. The smaller surface area of the lacrosse ball mobility set allows you to apply precise pressure to areas commonly stressed by HYROX training, including the glutes, hip flexors, calves, and upper back that a traditional foam roller cannot always reach.

For athletes combining high running volume with sled pushes, lunges, and loaded movements, maintaining mobility is not just about feeling better and preventing injuries. It helps you move efficiently, maintain good mechanics, and continue stacking quality training sessions.

"Make sure you sleep well. As most people don't even sleep properly."

— Alexander Rončević

It's worth repeating Rončević's simple back-to-the basics advice. We all know it, but do we really act on it.

Recovery is where the small details start to separate good athletes from great ones. Research has linked adequate magnesium intake with improved sleep quality, particularly in individuals with low magnesium status or sleep difficulties. Magnesium glycinate is one of the most popular recovery supplements among endurance athletes because magnesium plays a key role in hundreds of processes involved in muscle function, energy production, and nervous system regulation.

The benefit may extend beyond physical recovery. Training for an event like HYROX is mentally demanding, and race day often brings a mix of excitement, pressure, and nerves. Research has found that magnesium supplementation may help support a healthier stress response and reduce subjective feelings of anxiety in certain populations, particularly those with lower magnesium status.

For an athlete preparing for a major competition, the goal isn't a magic supplement that creates performance overnight. It's building a recovery routine that keeps your nervous system calm, your sleep consistent, and your body ready to handle another hard session tomorrow.

Magnesium is one of those small habits that can complement the bigger fundamentals Rončević built his career around: training consistency, nutrition, and recovery.

Recovery between hard sessions determines whether you can keep progressing. Covering the fundamentals like sleep, nutrition, and adequate mineral intake is an integral part of that performance equation.

The Takeaway

"The race is 1 percent of the whole journey. You had months of hard training. You did something for yourself, for your body and for your mind."

— Alexander Rončević

Alexander Rončević became the HYROX World Champion while teaching eight-year-olds their times tables. He built his running from 20km a week over a decade. He trained specifically for the fatigue he'd face on race day, not the fitness he'd feel in a fresh gym session. And he went home, slept well, worked on his mobility, and did it again the next day.

None of it necessarily required quitting his job. He quit eventually because HYROX got big enough that it made sense. The world championship came first.

As we always say at Sixpack Snacks: if you want to be the best, practice the habits of the best.
