HYROX asks a lot of you. You need to run eight kilometres across the race, but you also need the strength to push and pull a sled, the muscular endurance to get through lunges and wall balls, and the conditioning to keep running when your legs are already fatigued.
That can make training for it complicated. If the race tests all of those qualities, should you be training all of them from day one?
Former professional rugby player and HYROX World Championship qualifier Ben Seymour takes a different approach. Give yourself time, build the foundations first, then make your training progressively more specific as race day gets closer.
Here’s how a 16-week HYROX training block could take shape.
Before you start: work out where your gaps are
There is no single HYROX training plan that will suit everyone.
If you already have a strong strength base but running is your weakness, your training should reflect that. If you’re an experienced runner but lack the strength for the sleds, lunges and other stations, your priorities will look different.
Your training history counts too. Ben can tolerate running volumes built on years of professional sport and endurance training. Someone coming from a much lower training base shouldn’t simply copy the weekly kilometres of an experienced athlete and expect the same result.
Start by looking at what you can already do, where your biggest gaps are and how much training your body is currently accustomed to. Your 16-week plan should build from there.
Phase 1: Build your aerobic base and strength
The first part of Ben’s approach puts the emphasis on easy running and general strength.
For someone without much of a running background, he suggests spending the first four weeks building towards being able to run 8–10km, with around three to four runs per week where possible.
At the same time, build general full-body strength through movements such as squats, lunges, deadlifts and upper-body pushing and pulling.
Why start here?
Think of your aerobic fitness as the base of a pyramid. The wider that base becomes, the more capacity you have to build higher-intensity work on top of it later.
And while HYROX has plenty of obvious strength demands, strength also contributes to how much power you can produce on the SkiErg and rower. Building both foundations early gives you something to work with when training becomes more specific.
Phase 2: Add intervals and threshold training
Once you’ve established that base, you can begin introducing more intensity through interval and threshold work.
Threshold training teaches you to sustain a faster pace without pushing so hard that the effort quickly becomes unsustainable. That has an obvious application to HYROX, where going out too hard can cost you later in the race.
Ben identifies this as a common mistake: starting the first run too fast, pushing beyond a sustainable effort and then arriving at the SkiErg already struggling.
Interval training can also help develop your higher-end aerobic capacity and your ability to recover between harder efforts.
The goal at this stage isn’t to abandon your aerobic base. It’s to start layering speed and intensity on top of it.
Ben also builds deload periods into the wider 16-week structure, giving the body an opportunity to adapt before another block of progressive training.
Phase 3: Start running on tired legs
Around halfway through the block, Ben starts introducing compromised running. This is where HYROX training begins to look much more like HYROX itself.
Instead of always separating your running and strength work, you begin combining them:
- Sled push > run
- Sled pull > run
- Lunges > run
The reason is simple. During a HYROX race, you don't begin every kilometre feeling fresh. You have to transition out of a station and start running again while carrying fatigue from the work you've just done.
Being able to run 8km when fresh therefore doesn't tell you everything about your ability to run well during HYROX.
Compromised running gives you an opportunity to practise those transitions, understand what different efforts cost you and learn how to settle back into your running pace after a station.
Phase 4: Make your training look more like the race
As race day gets closer, training becomes increasingly specific.
That means more compromised running, more familiarity with the HYROX movements and more work using the loads you'll encounter in competition.
Simulations can also start playing a bigger role. They give you an opportunity to practise pacing, transitions and performing the movements under fatigue.
But that doesn't mean repeatedly completing a full HYROX in training.
Ben points out that a full race simulation can create a significant recovery demand, particularly for someone newer to the event. You can shorten running distances or use partial simulations to get many of the benefits without needing days to recover afterwards.
The aim is to do enough that race day feels familiar, while still being able to recover and continue training.
What could a five-day HYROX training week look like?
There isn't one weekly split that will work for everyone, but Matt and Ariel explored what a five-day week could look like for someone entering the block with a relatively balanced strength and aerobic base.
Early in the training block:
- 2 aerobic sessions
- 2 strength sessions
- 1 combined session, using some HYROX movements at reduced distances or intensity
As your aerobic and strength foundations develop, that could progress towards:
- 1 steady-state aerobic session
- 1 threshold session
- 1 interval session
- 2 resistance training sessions
Closer to race day, more of those sessions can begin incorporating compromised running and race-specific work.
The exact split should still reflect you. If running is already your biggest strength, you may need a greater strength emphasis. If you’re strong but struggle aerobically, the opposite may be true.
Don't forget the training you have to recover from
A 16-week HYROX build can involve a significant amount of work, and adding more training isn't always the answer.
Recovery, rest and food have to support the amount of training you're asking your body to complete. You need enough fuel to perform the work in the first place, and enough to recover and adapt afterwards.
That also means accounting for everything outside the gym. Your training history, work, lifestyle and current capacity all influence how much load you can realistically tolerate.
Your HYROX training should evolve as race day gets closer
A HYROX race requires running, strength, power, muscular endurance and the ability to perform all of them under fatigue. Trying to maximise every one of those qualities at the same time can make it difficult to give any one of them enough focus.
A 16-week structure gives you time to change that focus.
Build your aerobic and strength foundations first. Introduce threshold and interval work as your capacity improves. Begin combining running and stations around the middle of your preparation. Then make your training increasingly specific as race day approaches.
You don't need to train the entire race from day one. You need to arrive at race day prepared for it.
TL;DR
(Too Long, Didn't Read)
- Start your HYROX training by identifying your biggest gaps rather than copying someone else’s plan
- Build your aerobic base and general strength before adding lots of high-intensity or race-specific work
- Introduce intervals and threshold training once you have the foundations to support them
- Add compromised running around halfway through your preparation so you learn to run under fatigue
- Make training increasingly race-specific as race day gets closer, without relying on full race simulations every week
- Your training load needs to match your experience, lifestyle and ability to recover
