Why Your Running Pace Matters More in HYROX Than Your Sled Push

By Karyn Guidry, Exercise Physiologist & HYROX Coach

The sled push gets a lot of attention in HYROX training. It’s heavy, it’s uncomfortable, and it can feel like the moment that makes or breaks your race.

But here’s something I want more HYROX athletes to understand:

For many athletes, improving running pace can have a bigger impact on their overall HYROX finish time than getting faster at the sled push.

As a HYROX athlete and coach, I know how tempting it is to focus on the toughest workout stations. They’re challenging, they’re memorable, and improving them feels rewarding.

But HYROX isn’t decided by one station. It’s about how well you perform across the entire race.

That doesn’t mean the sled push isn’t important. A major slowdown there can absolutely cost you valuable time. The difference is that running shows up eight times throughout a HYROX race, while the sled push is just one station.

Let’s break down why your running pace matters, how it affects your finish time, and how to balance your HYROX training for better race-day performance.

Why Is Running So Important in HYROX?

A standard HYROX race alternates eight 1-kilometer runs with eight functional workout stations, totaling 8 kilometers of running.

That means you’re repeatedly switching between running and demanding strength or endurance movements.

And here’s what makes running so important:

Every second you gain or lose during each kilometer adds up across the race.

For example, let’s say you improve your average running pace by just 5 seconds per kilometer.

Average pace improvement Total time saved over 8 km
5 seconds/km 40 seconds
10 seconds/km 1 minute 20 seconds
15 seconds/km 2 minutes
20 seconds/km 2 minutes 40 seconds

These are illustrative savings, assuming your station and transition times remain unchanged.

You don’t necessarily need a dramatic breakthrough at one workout station to improve your overall HYROX time.

Sometimes, small improvements in your running pace can produce meaningful results because you’re repeating that effort eight times.

That’s why I encourage athletes to think about running as a major part of their race strategy, not just something they do between stations.

Running Can Account for a Large Share of Your HYROX Race Time

One reason running pace deserves so much attention is the amount of time athletes spend running during a HYROX race.

In a study examining a simulated HYROX event, participants spent an average of:

  • 51.2 minutes running
  • 32.8 minutes completing workout stations

In that simulation, running accounted for approximately 61% of the combined running and station time.

The exact percentage will vary depending on your fitness level, division, station performance, and race conditions. These figures also don’t necessarily represent every second spent in transitions.

Still, the takeaway is important.

Running can account for a substantial portion of your total HYROX performance.

Think about that for a second.

You could spend weeks trying to shave a few seconds off your sled push, but improving your ability to maintain a slightly faster pace across eight kilometers may create an even bigger opportunity.

That doesn’t mean you should neglect strength training.

It means you need to give your running the attention it deserves.

The HYROX Sled Push Matters, but It’s Only One Part of the Race

Now, don’t get me wrong.

The sled push absolutely matters in HYROX.

If you’re underprepared, it can become one of the most challenging parts of your race.

The sled push demands strength, force production, body positioning, and the ability to keep moving under significant resistance.

It can also leave your legs fatigued, making the next run feel much harder.

Another factor athletes sometimes overlook is that sled resistance can feel different depending on the competition surface and conditions.

That means your sled performance may vary between venues, even when your strength and preparation haven’t changed significantly.

Why You Still Need to Train the Sled Push

I always encourage athletes to develop enough strength and technique to move the sled efficiently.

You want to avoid unnecessary stops, wasted movement, and excessive fatigue.

But here’s the distinction:

The sled push can become a major bottleneck. Your running pace influences the rhythm of your entire race.

If the sled is a major weakness, improving it may be one of your biggest opportunities to save time.

However, once you can complete it efficiently, continuing to chase small improvements at that one station may not deliver as much benefit as improving your running across all eight kilometers.

The goal is to become well-rounded, not just exceptional at one movement.

Your HYROX Running Goal Is a Repeatable Pace, Not Your Fastest Kilometer

One of the biggest pacing mistakes I see athletes make is starting their HYROX race too aggressively.

It’s easy to feel strong during that first kilometer.

Your legs are fresh, your adrenaline is high, and you’re excited to get moving.

But HYROX running is very different from running eight fresh kilometers.

Each run is followed by a demanding workout station, and the later runs happen after you’ve already accumulated significant fatigue.

That means a pace that feels comfortable early in the race might become much harder to maintain later.

Why Starting Too Fast Can Hurt Your HYROX Finish Time

Let’s say you run your first kilometer significantly faster than your sustainable race pace.

You might gain a few seconds early.

But if that effort leaves you struggling through later runs or arriving at stations already exhausted, you could lose considerably more time.

That’s why I tell athletes:

Your goal isn’t to run your fastest first kilometer. It’s to find the fastest pace you can realistically repeat throughout the race.

A strong HYROX running strategy requires pacing discipline.

You want to maintain a controlled effort while preserving enough energy to move efficiently through the workout stations.

What Is Compromised Running in HYROX?

Compromised running is running while you’re already experiencing fatigue from another exercise or workout station.

For example, running immediately after sled pushes, burpee broad jumps, or sandbag lunges.

Your breathing may be elevated, your legs may feel heavy, and your normal running rhythm can become harder to maintain.

This is one of the reasons HYROX-specific running practice matters.

You need to develop the ability to settle into a sustainable pace even when your body is tired.

Being able to run fast on fresh legs is helpful. Being able to maintain your pace under fatigue is what makes that fitness more useful in HYROX.

How to Balance Running and Strength Training for HYROX

So, does this mean you should stop focusing on the sled push and spend all your time running?

Absolutely not!

The best HYROX training plans develop both running endurance and the strength needed to perform the stations efficiently.

Here’s how I recommend approaching that balance.

1. Build Your Aerobic Base

Your aerobic base supports your ability to sustain effort throughout the race.

Easy, controlled running helps develop the endurance foundation needed for longer workouts and repeated running efforts.

Not every run needs to be fast or exhausting.

Consistent aerobic training is an important part of preparing your body for the demands of HYROX.

2. Practice Controlled Faster Running

Once you’ve established a solid running foundation, include appropriately programmed sessions that challenge your ability to maintain faster paces.

Depending on your experience and training plan, these might include tempo runs, intervals, or race-pace efforts.

The goal isn’t simply to run faster.

It’s to become more comfortable maintaining a challenging but sustainable effort.

3. Include Compromised Running Workouts

Practice transitioning from functional movements into running.

For example, a training session might combine controlled running intervals with sled work, lunges, or other HYROX-specific movements.

These workouts help you understand how your running pace changes after demanding stations.

They also give you opportunities to practice controlling your breathing, managing fatigue, and finding your running rhythm again.

4. Keep Training Your Sled Push

Even if running is a major opportunity for improvement, you still need the strength and technique to complete the sled push efficiently.

Practice proper body positioning, controlled movement, and maintaining momentum.

You don’t want the sled push to become a weakness that costs you unnecessary time and energy.

5. Practice Your Race-Day Pacing Strategy

Don’t wait until race day to discover whether your target running pace is sustainable.

Use your training to understand how different paces feel, especially after completing demanding workout stations.

Pay attention to how your breathing, legs, and overall effort change as fatigue builds.

The best race pace is one you can sustain while still performing effectively at the stations.

Final Thoughts

As a HYROX athlete and coach, I want you to remember one thing:

HYROX isn’t about being the strongest athlete at one station. It’s about managing your effort and performing consistently across the entire race.

The sled push might be the station everyone remembers.

It’s challenging, it demands strength, and it can absolutely influence your race.

But your running pace affects eight separate sections of the event.

For many athletes, improving their ability to maintain a consistent running pace is one of the most effective ways to improve their overall HYROX finish time.

Keep building your strength. Keep practicing your stations. But don’t underestimate what better running endurance and smarter pacing can do for your performance.

Run consistently. Manage your effort. Stay strong through every station.
