Stephen Pelkofer on HYROX Training Metrics, Burpee Gains and Elite Performance

Stephen Pelkofer has established himself as one of North America’s leading HYROX athletes, and alongside Dylan Scott, he’s also become part of one of the fastest Pro Doubles partnerships in the sport, while building a growing reputation as one of HYROX’s most analytical thinkers.

A former data scientist, Pelkofer left a successful career to pursue HYROX and coaching full-time. In this episode of the Rox Lyfe Podcast, he explains why he made that decision, the training philosophy that has fuelled his rapid improvement, and why he believes many athletes focus on the wrong things in training…

 

From Data Scientist to Full-Time HYROX Athlete

Leaving a secure career in data science wasn’t a decision Pelkofer took lightly.

After building a successful career that included working in sports analytics with the NBA’s Oklahoma City Thunder before moving into the technology sector, he reached the point where he felt he had to fully commit if he wanted to see what he was capable of in HYROX.

“I felt like I had to go all in if I had any chance of being successful in this space.”

He spent weeks discussing the decision with his wife, even building financial projections before handing in his notice. While there were moments of doubt, he kept returning to one question.

“What’s the worst that could happen?… I take this little one-year hiatus trying to pursue something that very few people have the opportunity to pursue, and then I just go back to being a data scientist.”

Looking back, he believes that decision accelerated both his own performances and the growth of his coaching business.

 

How Basketball Prepared Him for HYROX

Unlike many elite HYROX athletes, Pelkofer didn’t come from running or endurance sports.

Instead, he played basketball throughout his childhood before competing at collegiate level, where he won a national championship.

While basketball might not seem an obvious pathway into HYROX, Pelkofer believes it built exactly the combination of aerobic fitness, repeated high intensity efforts and explosiveness that translates well into the sport, particularly in Pro Doubles.

He also believes the years spent competing helped develop the mindset and discipline that continue to drive his progression today.

 

What He’s Learned From Training With Dylan Scott

One of the biggest turning points in Pelkofer’s career came after moving to North Carolina, where he discovered he lived just minutes away from Dylan Scott (2026 HYROX World Champion).

The pair began training together regularly before eventually forming one of the strongest Pro Doubles teams in the world.

For Pelkofer, the biggest lesson hasn’t simply been watching one of the world’s best athletes train.  It’s been seeing the consistency behind it.

Whether Scott is training in a garage, a hotel gym or before catching a flight, he always completes the work.

Pelkofer says that level of commitment has raised his own standards, while the pair constantly exchange ideas and challenge each other’s thinking on training.

 

Why HYROX Is Primarily an Aerobic Sport

One of Pelkofer’s strongest beliefs is that HYROX athletes often misunderstand what the sport really demands.

Despite the heavy sleds and functional stations, he believes success is driven primarily by aerobic fitness.

“Even the best in the world are out there for fifty-two minutes. It is primarily an aerobic event, and you should train things aerobically.”

That philosophy influences almost everything he does.

Rather than chasing maximum strength numbers, Pelkofer focuses on building muscular endurance, improving his aerobic engine and becoming more efficient at the movements that actually decide race performance.

 

Why He Rarely Uses Heavy Barbells

That philosophy also explains why Pelkofer has largely abandoned heavy squats and deadlifts.

While many athletes still see maximum strength as a major priority, he believes those lifts offer relatively little return once a solid strength base has been established.

“There are way stronger guys than me who aren’t pushing the sled as fast as me.”

Instead, he prefers heavy lunges, sled work and race-specific muscular endurance training that more closely resembles what athletes experience during a HYROX race.

Heavy barbell work still has a place in his training, but mainly during the off-season rather than race preparation.

 

How He Cut More Than 90 Seconds From His Burpee Broad Jumps

Pelkofer has reduced his burpee broad jump split from 3:52 to just 2:20 across twelve races.

The improvement didn’t come from one technical breakthrough.

Instead, it came from repeatedly practising the movement in training.

“If you just do a lot of volume consistently with burpees, you’re probably going to get more efficient at it. It’s almost like running economy, but like burpee economy.”

He regularly performs burpee-to-plate intervals at different intensities, allowing him to improve technique, rhythm and efficiency without constantly pushing maximal effort.

Combined with a stronger aerobic base, those gains have transformed one of his biggest weaknesses into one of his strongest stations.

 

The Training Metrics He Tracks Every Day

Pelkofer’s background in data science remains central to his training.

He has built his own internal dashboard that records virtually every aspect of his workload, including training minutes, running mileage, burpee volume, wall balls, session RPE and overall training load.

Rather than relying entirely on wearable devices, he combines objective metrics with subjective feedback to understand how his body is responding.

That detailed tracking allows him to compare training blocks over months and years while making informed adjustments based on evidence rather than guesswork.

 

Polarised Training: Easy Days Easy, Hard Days Hard

Another major theme throughout the conversation is intensity management.

Pelkofer follows a highly polarised approach where genuinely hard sessions are separated by genuinely easy recovery work.

He believes many athletes fall into the trap of training in the middle every day.

“I think people don’t realise they’re working at a five or six out of ten every single day. They never hit their top gear, but they’re also never go easy enough to recover from the work they’re doing.”

By keeping easy days easy, he arrives at key workouts fresh enough to produce meaningful adaptations while remaining consistent week after week.

 

Final Thoughts

Stephen Pelkofer’s approach to HYROX is built on evidence, consistency and patience.

Rather than searching for shortcuts, he focuses on repeatedly executing the training that directly improves race performance, measuring the results and refining the process over time.

Perhaps his most encouraging message is that recreational athletes don’t need to copy the training volume of the world’s best.

“You don’t need to have Dylan Scott’s training volume to see progress. I ran a sub-60 HYROX on about seven and a half hours of training a week.”
