To kit up for a home HYROX simulation, wear your tested race-standard top and shorts, stable hybrid trainers, and set up substitutes for the 8 stations, a backpack for the sled, dumbbells for the farmers carry, a rucksack for lunges. As of 2026 the aim is to rehearse race kit and pacing together, so the simulation tests your clothing under real fatigue, not just your fitness.

• A HYROX is 8×1km runs plus 8 stations, so a home simulation needs a running route and 8 improvised stations.
• Wear the exact kit you plan to race in, the Tech Short v2 and Tech T-Shirt Race Team v2 are built for this repeated high-output work.
• In THETA's coaching data, simulations are where kit chafing and slipping first appear, before race day.

What kit should you wear for the simulation?

Here's the simple version: dress exactly as you would on race day. That means a fitted, sweat-wicking technical top and lunge-proof shorts you haven't yet properly tested over 60 minutes of continuous work. THETA's Tech Short v2 and Tech T-Shirt Race Team v2 are made for repeated high-output efforts, with open ventilation that doesn't cling when soaked, which is precisely what a simulation demands. If you're planning to race in the Race Singlet or Race Short, wear those. The whole point is to soak the kit the way race day will, so any chafing at the thigh, underarm or shoulder turns up now, while you can still change your mind.

How do you improvise the 8 stations at home?

You won't have official equipment, and that's fine, because you can still rehearse the movement patterns and the kit demands closely. A loaded backpack dragged on a smooth surface or pushed against resistance stands in for the sled, dumbbells or kettlebells cover the farmers carry, a heavy rucksack held to the chest covers sandbag lunges, and a medicine ball or dumbbell thruster to a wall mark covers wall balls. The distances matter less than the time under tension and the sweat load, because those are what test your kit. Run the 1km efforts on a measured route or treadmill between each improvised station to recreate the compromised running that soaks and stresses your clothing.

Why does kit choice matter in a simulation?

A simulation is the safest place to find a kit problem, since the cost of failure is a ruined session rather than a ruined race. Chafing, ride-up on lunges and a top clinging when soaked only show up under sustained effort, and 60 to 90 minutes of continuous work recreates that nicely. Running it in unproven kit tells you whether the shorts stay put through improvised lunges, whether the top stays light once fully soaked, and whether any seam rubs. By the time you race, the kit is a known quantity, and that removes one of the biggest avoidable race-day variables, which is rather the point of rehearsing at all.

How do you run the simulation start to finish?

Structure it to mirror the race and test both kit and pacing.

1. Warm up in a shed-able layer, then strip to your race kit before starting.
2. Run 1km, then complete each improvised station in race order.
3. Note any chafing, slipping or ride-up as it happens, do not ignore it.
4. Keep transitions short to rehearse the roxzone and how kit feels moving.
5. After finishing, review kit performance and pacing before your next block.

"A home simulation is where you find out what race day would have taught you the hard way. Wear the kit you intend to race in, soak it, lunge in it, and let it prove itself before it counts," says the THETA coaching team.

Common questions

What should I wear for a home HYROX simulation?

Wear the exact race kit you plan to compete in, a fitted sweat-wicking top and lunge-proof shorts, plus stable hybrid trainers. The simulation should test your clothing under fatigue, not just your fitness.

How do I replicate HYROX stations at home?

Use a loaded backpack for the sled, dumbbells for the farmers carry, a heavy rucksack for lunges and a med ball for wall balls. Run 1km between each on a measured route to recreate compromised running.

Why should I test kit in a simulation?

Because chafing, ride-up and clinging fabric only appear under sustained effort, and a simulation exposes them safely. Discovering a kit problem in training costs a session, discovering it on race day costs the race.

Can I use my normal training kit?

Use whatever you intend to race in, provided it is race-standard and sweat-wicking. THETA's Tech Short v2 and Tech T-Shirt Race Team v2 are built for exactly this repeated high-output work.

How long should a home simulation last?

Aim for 60 to 90 minutes of continuous work to match typical Open finish times and fully soak your kit. That duration is what reveals both pacing weaknesses and clothing problems.

Do the exact station weights matter at home?

Less than the time under tension and sweat load, which are what test your kit and pacing. Match the movement patterns and continuous effort rather than chasing precise HYROX weights.

What should I do after the simulation?

Review both kit performance and pacing, noting any chafing or slipping, then adjust your choices before the next block. A programmed plan can turn those findings into the next weeks of training.
