5 Hyrox Training Mistakes Your Clients Are Making (And How to Fix Them)

Your clients are putting in the hours. They're sweating through the workouts you program. But when they cross the Hyrox finish line, their time is still not where it should be. It's a frustratingly common problem for coaches, and the solution often isn't to just increase their training volume.

More often than not, stagnant race times are the result of a few critical, yet easily fixable, training mistakes. We've spent hours digging through discussions on Reddit's r/hyrox and talking with coaches to identify the most common traps that even dedicated athletes fall into.

As a coach, your ability to spot and correct these mistakes is what separates you from a generic training plan. Here are the five biggest mistakes to look for and how to fix them in your clients' programming.

Mistake #1: Their "Race Pace" Is a Myth

This is the single biggest mistake you'll see. Athletes train their running and their station work completely separately. They might do a 5k run at a steady pace on Monday and a series of sled pushes on Tuesday. But they rarely, if ever, practice running at their target race pace immediately after a taxing station.

As one Reddit user wisely noted, the first half of a Hyrox race is more taxing on the legs. If you haven't programmed compromised running for your clients, their pacing strategy will fall apart before they even reach the halfway point.

The Fix: Program Compromised Running

• What it is: Compromised running means doing a run immediately after a strength movement to simulate race conditions.
• How to program it: At least once a week, your clients' workouts should include a block like this:
  • 400m run @ target race pace
  • 20 Wall Balls
  • 400m run @ target race pace
  • 20m Sled Push
  • 400m run @ target race pace
• Why it works: This teaches an athlete's body to clear lactate while running and helps them find a sustainable "race pace" that is realistic under fatigue. It's one of the most effective tools in your coaching arsenal.

Mistake #2: They Only Repeat Stations, They Don't Progress Them

Many training plans, especially free ones, fall into the trap of simply having athletes do the eight Hyrox stations over and over. While practice is important, repetition without progression leads to plateaus.

Your job as a coach is to apply the principle of progressive overload to the Hyrox movements, just as you would with traditional strength training.

The Fix: Isolate and Overload in Your Programming

• Isolate the movement: Dedicate one training day to focus on the strength and technique of just 2-3 stations. For example, a sled-focused day.
• Apply progressive overload: Don't just have your clients do the race weight. Vary the stimulus.
  • Heavier Sled Pushes: Program 25% heavier than race weight for shorter distances (10-15m) to build raw power.
  • Lighter, Faster Sled Pushes: Program 25% lighter than race weight for longer distances (50m) to improve speed and efficiency.
  • Volume Overload: Increase the total number of reps or sets for movements like Wall Balls or Lunges.

Mistake #3: They Ignore Prehab and Joint Care

Hyrox is tough on the body. The combination of high-volume running and heavy, functional movements puts a massive strain on your clients' joints, especially their knees, hips, and lower back.

Too many athletes wait until they are injured to think about mobility and stability. By then, it's too late. As a coach, you need to make proactive joint care, or "prehab," a non-negotiable part of their training week.

The Fix: Schedule and Program Prehab

• Make it a priority: Dedicate at least two 20-30 minute sessions per week in their program to mobility and stability work. Don't just tack it on at the end if they have time.
• Focus on key areas:
  • Hips: Program hip flexor stretches, 90/90s, and banded glute bridges.
  • Ankles: Program ankle circles, calf stretches, and banded dorsiflexion.
  • Thoracic Spine (Upper Back): Program cat-cow, foam rolling, and thoracic rotations.
• Educate your clients: Teach them to listen to their bodies. If they feel a tweak or persistent soreness, they need to communicate that to you so you can adjust their program before it becomes a full-blown injury.

Mistake #4: They Start Too Fast on Race Day

The adrenaline is pumping, the crowd is roaring, and everyone around them sprints out of the starting gate. It's incredibly tempting for an athlete to get caught up in the initial excitement and go out way too hot. This is a fatal error that you must coach them to avoid.

As one experienced Hyrox athlete on Reddit advised, "Wait 20 seconds after everyone else has run off. Your time starts when you cross the timing mat." Going from 0 to 100 in the first 200 meters will spike their heart rate, flood their legs with lactate, and they'll pay for it dearly on the sled push.

The Fix: Coach The First Kilometer Rule

• Drill it into them: Their only goal for the first 1km run is to settle in. They need to find their rhythm and keep their heart rate under control.
• Give them a target: Tell them to aim for their target race pace + 15-20 seconds for the first kilometer. They can make up this time later in the race when others are fading.
• Remind them to focus on their own race. They need to ignore the people sprinting past them and trust the training and pacing strategy you've developed together.

Mistake #5: They Don't Have a Coached Nutrition Strategy

One of the most painful (and funny, in hindsight) stories on Reddit came from an athlete who did their first Hyrox with zero nutrition plan. They didn't carb load, didn't take electrolytes, and completely bonked halfway through the race.

Hyrox is an endurance event that can last anywhere from 60 to 120+ minutes. You cannot let your clients rely on just a good breakfast to get them through it. Their performance on race day is directly linked to how you coach them to fuel their bodies.

The Fix: Provide a Simple Fueling Plan

• Coach the Carb Load: In the 2-3 days before the race, instruct them to increase the percentage of carbohydrates in their diet. They don't need to stuff themselves, just shift the balance of their macros.
• Prescribe Electrolytes: Tell them to start sipping on an electrolyte drink the day before the race and have some on the morning of. Explain that this is essential for muscle function.
• Plan their Race Day Breakfast: Give them a list of familiar, easily digestible meals rich in carbohydrates to eat 2-3 hours before their start time. Oatmeal, bananas, and bagels are common choices. Tell them what to avoid (high-fat or high-fiber foods).
• Plan for Intra-Race Fuel (Optional): For clients who you expect to take longer than 90 minutes, have a plan for an energy gel around the 60-minute mark.

As the unofficial Hyrox coaching app, TrainingPro makes it easy to program all of these elements—from compromised running to prehab sessions—and deliver them to your clients in a clean, professional interface.
