Emma Kirk-Odunubi found her love for movement early on, using sport to feel strong and get through tough times. Since then, she’s run 14 marathons (including an ultra!) and tackled two HYROX World Championships. Now, she’s sharing her top training tips and a simple running plan to help you smash your running at your next HYROX race.
All runners come into this sport at different points. Some of you may never have run before, while others may be experienced runners with years of mileage. Meet yourself where you are at. If that means starting with a couch to 5k programme, then building to 10k – do it. But why 10k? The entire race consists of 8 × 1k runs, but by the time you conquer the stations and move through the Roxzone, you will likely cover closer to that 10k marker. If you’re reading this as an experienced runner or someone looking to chase a time, test your pace for a 10k beforehand. Can you hold the pace you want for HYROX over 10k without stations in between? This will be a great indication of your ability to hold pace.
Whichever camp you fall into, a 10k benchmark is a great initial starting point. Your run plan below will be based on being able to run for 50 minutes already. If this isn’t you, slowly look to build your longest run by 5 minutes weekly.
To run faster, we won’t be running at maximal effort all the time. A phrase I say a lot is run slow to run fast. This is where the science comes in. Slow runs build endurance. They train your heart, lungs, and muscles to keep going for longer, as well as building your aerobic system.
Your aerobic system is how your body fuels your muscles by using oxygen to turn carbohydrates and fat into the energy we need to live and exercise. The more efficient our aerobic system, the stronger our base of fitness. The bigger our base, the more efficient the system, and the longer we can hold faster paces.
Therefore, in this plan, one of your runs will be a long, slow, easy run that will build in distance/time over the weeks. This run will be at a beautifully slow conversation pace. If you had to rate the perceived effort (RPE) out of 10, with 10 being maximal, this run would register a 4. See the explanation of RPE below.
1 – Very light exertion
Minimal effort, such as walking slowly or gentle stretching. Feels easy and comfortable.
2 to 3 – Light activity
You could sustain this effort for hours. Breathing is calm, controlled, and conversational. Great for recovery or gentle warm-ups.
4 to 6 – Moderate activity
You’re breathing more heavily but still able to talk in full sentences. Feels comfortable but purposeful – this is your “easy” or “long run” zone where endurance builds.
7 to 8 – Vigorous activity
You’re working hard. Breathing is heavier, conversation is limited to short sentences, and effort feels challenging. This is your speed or interval training zone.
9 – Very hard activity
You can only say a few words at a time. Your heart rate is high, effort is intense, and maintaining pace feels tough.
10 – Max effort
All-out exertion. Feels almost impossible to sustain for more than a short burst – this is your limit.
In this plan, you’ll focus on three main types of runs each week:
Easy Run
A slow, comfortable run designed to build endurance and aerobic capacity. You should be able to hold a conversation easily during this run. This run helps strengthen your heart, lungs, and muscles without excessive fatigue.
Speed or Interval Run
This session involves running at a high intensity – usually intervals or tempo efforts faster than your goal HYROX race pace. The goal is to teach your body and mind to handle faster speeds and to improve your lactate clearance, which helps delay fatigue during the race.
Long Run
A longer, slow-paced run designed to improve endurance by increasing your time on your feet. This run builds your aerobic base and mental toughness, and it gradually increases over the 10 weeks up to 90 minutes.
Your first week sets the foundation. The goal is to find your current fitness level and start building consistency.
Here’s your breakdown:
Now that you’ve set your baseline, we begin adding volume.
Here’s your breakdown:
This week is all about refining pacing and sustaining speed under fatigue.
Here’s your breakdown:
We start layering in more sustained efforts.
Here’s your breakdown:
This week allows your body to recover while testing progress.
Here’s your breakdown:
Now we begin to train closer to race intensity.
Here’s your breakdown:
This week mirrors the previous one but with added volume to increase challenge.
Here’s your breakdown:
This is your biggest week before tapering.
Here’s your breakdown:
Time to pull back before race week.
Here’s your breakdown:
This is it – race week! Keep everything light and sharp.
Here’s your breakdown:
With this 10-week HYROX running plan, you’ll build a strong aerobic base, improve your speed, and prepare both body and mind for race day. Consistency, smart training, and combining this run plan with your strength and HYROX-specific workouts will set you up to crush your next event. Stay patient, listen to your body, and enjoy the journey to becoming your strongest HYROX runner yet!

How can I improve my 1km time for a HYROX race?
To improve your running, training is key. A HYROX race involves incorporating both workouts and running together, so being able to run when your legs feel a bit tired is essential. Mix up your run routine (lengths and distances) to build on your stamina and endurance, too.
What's the difference between a normal 5K and a HYROX race?
HYROX is an event that has both running and functional workouts, all combined to make this 'hybrid' event that many people love. A 5K is a running event that it simply running 5K; you may have heard of a Parkrun - that's usually a 5K race held on the weekend in the UK and everyone of all running abilities gathers to take part.
How should I train for a HYROX race, combining both strength and running workouts?
As mentioned above, learning to run on tired legs will help you in a HYROX race, so incorporate some 'compromised running' into your workout (completing an exercise and then running straight afterwards). Include a mix of strength training and running (long and interval runs, for example) in your training plan to hit all sections of your upcoming HYROX race.
