Hyrox Doubles Explained: Rules, Strategy & Prep

The Hyrox doubles race isn’t just a shared workout; it’s where strategy meets synchronicity. It’s the exact same format as the singles race, but now you’ve got a teammate in the trenches with you. And between you both, it becomes a constant negotiation of how well you manage pace, fatigue, and decision-making under pressure.

Competing with a partner is often considered more accessible than racing solo, and for good reason. You’re sharing the workload and buying back small moments of recovery, which can make the race feel more manageable. It’s still challenging, but for many, it’s also about pushing yourself alongside someone else and seeing what you can achieve together.

You’ll still run every kilometre side by side, but the real question is how you divide the work at each station. Who takes the lead? When do you switch? And how do you adapt when fatigue starts to chip away at your plan?

In this guide, we’ll walk you through everything you need to know about Hyrox doubles, from the rules and weights to training, race-day prep, and how to build a strategy that works for both of you.

Hyrox Doubles Rules & Race Overview

Whether you’re competing in the doubles or singles division, the format stays the same: 1km run, then a station, repeated 8 times.

Both athletes must complete all eight runs together. No splitting up, no pacing separately, so if one of you slows down, you both slow down. Otherwise, you face a time penalty*.

At the stations, you can split the work however you want. One partner can take on more work, alternate reps, or break things into smaller chunks based on your strengths.

The freedom can be a huge advantage; you can split the work however you like, but also where most teams lose time.

What Actually Matters on Race Day

This isn’t the time to figure it out as you go. The best performing teams treat the race like a script that they’ve already rehearsed.

Before race day, you should know:

• Your run pace from when you’re fresh to when you’re on the last few km’s

• Your station splits (who does what, and when), e.g., Farmer’s Carry: 20m each, no exceptions

• Your switching strategy (pre-planned, not reactive)

In-Race Execution Tips

• Switch before you start slowing down, not when you’re close to failure

• Try to keep reps clean to avoid costly no-reps

• Use simple cues (“5 more”, “switch”, “mine”)

• Commit to your plan unless it’s clearly breaking down

*Judges are present throughout to enforce movement standards and ensure reps count.

Hyrox Doubles Weights – Open vs Pro

Weights in doubles are not split between partners. You’re still working with full loads, just dividing the reps between you.

FYI: In HYROX Mixed Doubles, both partners use the Men’s Open weights (or Female Pro weights) for all stations, except for wall balls. This means female participants in mixed doubles lift heavier than in the Women’s Open category, matching the men's open weight standards.

How to Train for a Hyrox Doubles Race

Training for a Hyrox doubles race isn’t just about getting fitter for the event; it’s about getting in sync with your partner. You’re preparing as two athletes to perform as one unit, which means aligning pace, strengths, and decision-making when pressure’s high and so is your heart rate.

1. Pre-Plan Your Station Strategy

A doubles strategy needs to be planned with intent, being tactical about each station and asking yourself not just “who’s better than this?” but “how do we keep moving as fast as possible?”

Plan who starts each station, how you’ll split reps or distance, and when you’ll switch. Also consider taking the lead on each movement based on your strengths. For example:

• Sled Push: stronger athlete takes longer drives

• Row: pre-set splits (e.g. 300/200/300/200)

• Wall Balls: taller athlete takes the most reps

2. Rehearse Transitions & Communication

In Hyrox, hesitation is a hidden is a time penalty. The best doubles teams move through the stations like a smooth relay race.

To get to this point, you should rehearse:

• Running into stations at a pace

• Immediate handovers

• Clear, minimal communication

Communication is everything; snappy directions and body language mean everything on race day. The easier your partner is to read, the more confident you’ll feel going into each station.

Find the cues that work for you, e.g:

• “last 5”

• “switch”

• “mine”

Practice the cues mid-set so they begin to feel automatic, not like something you’re figuring out on the spot.

3. Build Complete Conditioning

Both athletes need well-rounded fitness, but in Hyrox, that doesn’t mean doing a bit of everything; it means training your body to produce force, absorb fatigue, and keep moving when things get tough.

What you actually need:

• Strength (for sleds, carries, lunges)

• Engine (for runs + ergs)

• Muscular endurance (for wall balls, burpees)

If one area drops off, it slows the whole team down. Focus on foundational lifts that translate to race demands:

The Movements That Carry Over

• Squats → lunges, wall balls, getting out of the hole under fatigue

• Deadlifts/hinge patterns → sled pull power, posterior chain strength

• Lunges (walking, alternating, loaded) → direct carryover to sandbag lunges

• Push strength (thrusters, push press) → wall ball efficiency and fatigue resistance

• Pull strength (rows, SkiErg patterns) → upper body endurance under load

• Carries (farmer’s, front rack, sandbag) → grip, core stability, and posture

Then Build Muscular Endurance on Top

Strength will get you through the first reps, but it’s endurance that decides whether you keep moving or stall. It’s about training your body to tolerate high effort without falling apart.

Layer in:

• Higher-rep strength work (think 12–20+ reps under control)

• Time-based sets (e.g. 60–90 seconds of continuous work)

• Carry intervals (walk, rest briefly, repeat)

• Wall ball volume under fatigue

4. Endurance Train Together

Both athletes run the full 8km, but it won’t feel like a clean 8km. It’s broken up by 8 high-intensity stations, meaning every run starts under fatigue.

It’s your only chance to recover slightly, but it’s also the bulk of your total race time, so this is where your aerobic capacity really needs to align.

When it comes to training, you should do it together where possible. If one of you is redlining early, it’s a problem that compounds across all 8 runs. Together you should:

• Be comfortable running 8–10km total per session

• Lock into a shared race pace you can both sustain

• Practise holding it after hard efforts, not just fresh

What does this look like in training?

• Interval runs (e.g., 1km repeats with short rest)

• Brick-style sessions: run → workout → run

• Tempo runs where you sit just below your threshold

Repeating these workouts will help teach your body to find control in moments you would usually panic.

5. Train For The Reality of the Race

The reality of Hyrox is that it doesn’t get easier at any point in the race. It’s a sustained level of discomfort throughout, without any rest or recovery time.

To prepare for this, your training should include:

• Intervals

  → to build repeatable effort

• Circuits

  → to link movements together under fatigue

• Compromised work

  → lifting or carrying straight after running

• Race simulations

  → to practise pacing and decision-making

The real skill isn’t just being strong or fit, it’s being able to:

• Pick up the sled when your legs are already heavy

• Hold onto carries when your grip is fading

• Hit wall balls without missing reps when your breathing is out of control

Important: The key session is your simulation day. This is where you practise splits, transitions, and pacing so nothing feels unfamiliar on race day.

Teamwork & Strategy Tips

This is where strong pairs separate themselves. It’s not just about fitness; it’s about how well you work together under pressure.

• How to split stations effectively:

  Don’t aim for a 50/50 split. Aim for the fastest overall outcome. That might mean one athlete does more work on certain stations while the other conserves energy for later.

• Communicating during transitions:

  Keep it simple and consistent. Short cues like “switch”, “stay”, or “last 5” work best when you’re fatigued.

• Supporting a slower partner without burning out:

  If one partner starts to struggle, avoid overcompensating too early. Instead, reduce the intensity and increase the number of switches to keep the output steady.

• Know each other’s strengths and weaknesses:

  Go into the race with a clear understanding of who handles what best. This helps you make quicker decisions and avoid hesitation when the clock is ticking.

• Adjusting the plan mid-race:

  No strategy is perfect. If something isn’t working, adapt. Smaller sets, quicker switches, and continuous movement will always beat stopping completely.
