What Is HYROX^® Relay

HYROX^® Relay is a four-athlete team format where each competitor owns exactly two of the eight workout stations and the two corresponding 1 km run segments. Instead of one athlete completing all eight stations across roughly 16 km of work, the total race effort is divided into four blocks — each block roughly 2–3 km of running and two consecutive stations.

The format attracts a different athlete profile than individual or doubles racing. Corporate teams, gym crews, and mixed-ability groups often start with relay because the individual burden is significantly lower — each athlete is on course for around 20–30 minutes depending on their station pairing and run speed. From the 700,000+ athlete profiles on ROXBASE, relay entries skew toward recreational competitors and first-timers using the format as a lower-pressure introduction to HYROX^® racing.

That said, competitive relay is a legitimate strategic discipline. The fastest relay teams exploit station-to-athlete matching in ways that individual racers cannot, and the transition execution requirements add a layer of race craft that separates well-prepared teams from those who just showed up.

Relay Format Rules

Station Pairing and Running Order

Each athlete completes two adjacent stations in the HYROX^® sequence plus the run segment that precedes each of their stations. The eight stations in order are: SkiErg (1,000 m), Sled Push (50 m), Sled Pull (50 m), Burpee Broad Jumps (80 m), Rowing (1,000 m), Farmer's Carry (200 m), Sandbag Lunges (100 m), and Wall Balls (100 reps).

The standard pairing breakdown is:

Athlete	Stations	Work Description
Athlete 1	SkiErg + Sled Push	Run km 1, SkiErg, run km 2, Sled Push
Athlete 2	Sled Pull + Burpee Broad Jumps	Run km 3, Sled Pull, run km 4, BBJ
Athlete 3	Rowing + Farmer's Carry	Run km 5, Rowing, run km 6, Farmer's Carry
Athlete 4	Sandbag Lunges + Wall Balls	Run km 7, Sandbag Lunges, run km 8, Wall Balls

Each athlete runs with the rest of the team during the 1 km segments that precede their stations — but only the active athlete does the station work. The other three team members wait in the transition zone.^[1]

Transition Zone and Chip Handoff

HYROX^® relay teams use a timing chip or baton that must be physically exchanged inside the designated transition zone — known as the Roxzone — between athletes. The outgoing athlete finishes their second station, returns to the Roxzone, and hands the chip to the incoming athlete. The incoming athlete then begins their first run segment.

Both athletes must be in the Roxzone simultaneously for a legal handoff. An early departure — where the next athlete starts before the chip transfer — results in a time penalty. Practise handoffs at race pace so the transition takes under five seconds. Fumbled chips and missed tags are where prepared teams gain time on unprepared competitors.^[2]

Weight Standards

Relay teams in the Open division use standard Open weights. The Sled Push is 102 kg (including the sled) for male athletes and 72 kg for female athletes. Athlete 1's sled assignment must match their sex-category weight. For mixed relay teams — which HYROX^® permits — each athlete uses the weight corresponding to their own sex category, regardless of team composition. Confirm weight standards with event organisers before race day, particularly for events outside the main HYROX^® series where variations occasionally appear.

The Station Assignment Framework

Four Athlete Archetypes, Four Blocks

The relay format's power is that you can match athlete type to station type with precision. Here is how to think about each block:

Block 1 — SkiErg + Sled Push (Athlete 1) This is the heaviest upper-body block in the race. SkiErg at 1,000 m demands sustained lat and shoulder endurance; Sled Push demands raw horizontal force output. The ideal Athlete 1 profile is a high upper-body strength athlete who can also tolerate two consecutive run kilometres at a moderate pace. Powerlifters, CrossFit competitors with strong pulling capacity, and rugby forwards often excel here.^[3]

Block 2 — Sled Pull + Burpee Broad Jumps (Athlete 2) Sled Pull is another absolute-strength station — rope-over-hand pulling of a loaded sled 50 m. Burpee Broad Jumps then demand hip explosiveness and aerobic tolerance. The combination rewards athletes who are both strong and can sustain elevated heart rates through a mixed-modal effort. Assign your second-strongest all-around athlete here, particularly one who handles high-rep explosive movements without spiking HR uncontrollably.

Block 3 — Rowing + Farmer's Carry (Athlete 3) This block shifts from raw strength toward aerobic capacity and grip endurance. Rowing at 1,000 m favours athletes with efficient technique and high aerobic output — the kind built by swimmers, cyclists, and distance runners who have added gym work. Farmer's Carry at 200 m (24 kg/16 kg per hand in Open) tests loaded walking under fatigue, which punishes athletes with poor posture and weak grip. Your most aerobically developed athlete with solid carrying mechanics belongs here.

Block 4 — Sandbag Lunges + Wall Balls (Athlete 4) The final block is where races are lost. Sandbag Lunges at 100 m (20 kg/10 kg Open) on legs already primed by running, followed by 100 Wall Ball reps at the end of the race. This is the most quad-dominant block. The ideal Athlete 4 profile is a cross-training athlete who thrives under sustained metabolic stress — someone whose technique stays intact when fatigue accumulates. If anyone on your team has competed in CrossFit or obstacle racing, this is their block.

How to Benchmark Before Assigning

Do not assign blocks based on gut feel. Run a simplified benchmark session four to six weeks before your event: each athlete completes their proposed block at race loads, with a 1 km run beforehand to simulate arriving pre-fatigued. Record split times and rate of perceived exertion. If two athletes are close in suitability for a given block, try both assignments and compare data.

ROXBASE percentile benchmarks for individual stations — drawn from 700,000+ athlete profiles — let you see where each team member sits relative to the competitive field for a given station, not just within your own team. That external reference point often reveals mismatches that internal comparisons miss.

Run Strategy for Relay Teams

Running Together vs. Splitting

HYROX^® relay rules require athletes to stay together during the shared run kilometres (the runs before each athlete's stations), but teams interpret "together" differently in practice. The practical standard: all four athletes should remain within the run corridor as a group. Sprinting ahead or dropping far behind disrupts team flow and risks penalty.

Set your run pace based on the slowest athlete on your team, not an average. In relay, this matters less for total time than in doubles — each athlete only runs 2 km total — but a team that fragments on runs arrives at the Roxzone at different times, creating transition confusion.^[4]

Pacing Each Block's Run Segments

Each athlete's two runs serve different purposes. The first run (before their first station) is an arrival — you want to hit your station with heart rate manageable and legs under you, not gasping. Run the first kilometre at roughly 70–75% effort. The second run (between the two stations) is a connector — you know exactly what is coming, so pace it to arrive at your second station in control. Run the second kilometre at 75–80% effort only if your second station is aerobic; pull back to 65–70% if it is a strength station where controlling heart rate matters more.

Transition Execution

The Roxzone Handoff Protocol

Every second in the Roxzone is dead time — no athletic output, no forward progress. The target is a handoff under five seconds from when the incoming athlete crosses back into the Roxzone to when the outgoing athlete starts their run. Achieving this consistently requires:

1. The finishing athlete announces their arrival with a clear verbal signal — "coming in" — before they reach the zone.
2. The next athlete is already standing at the handoff point, chip or baton in hand position, not fumbling for it.
3. Physical chip transfer happens, both athletes confirm verbally ("go"), and the next athlete moves immediately.

No high-fives, no conversation, no looking back. Save the celebration for the finish line.

Rehearsing Under Fatigue

The biggest rehearsal mistake relay teams make is practising transitions while fresh. On race day, the incoming athlete is breathless, grip is compromised, and coordination is degraded. Build two full relay simulation sessions into your preparation — complete the actual work before each transition so that handoffs happen under realistic fatigue conditions. Timed handoff drills done fresh give you false confidence.

For more transition and team coordination principles, the HYROX^® Doubles Strategy guide covers the underlying framework that applies equally well to relay handoffs.

Common Relay Mistakes and How to Fix Them

Ignoring Block Sequencing in Training

Most relay teams train individually and only come together for race day. The result: nobody has practised their specific two-station block under fatigue, let alone the handoff sequence. Build at least three joint training sessions into your race prep, each one focusing on a different pair of blocks together so every athlete experiences what it feels like to hand off after maximal effort.

Mismatching Athletes to Blocks by Ego

The athlete who is "best overall" does not automatically get the hardest block. Block 4 (Sandbag Lunges + Wall Balls) is not a reward for your strongest team member — it requires a specific combination of quad endurance, metabolic tolerance, and mental resilience late in the race. Assigning your strongest athlete to Block 1 and leaving Block 4 to someone who deteriorates under sustained fatigue is a common team-building error that shows up clearly in split data.^[5]

Underestimating Wall Balls

Wall Balls at the end of HYROX^® relay consistently produce the longest station splits relative to expectation. Athletes who perform well on Wall Balls in isolation — tested fresh, in training — frequently underperform at the end of a race block. Athlete 4 must test Wall Balls at the end of a hard training session, not as a standalone exercise. If they cannot hold sets of 20+ under fatigue, build that capacity explicitly in the eight weeks before the event.

Building and Selecting Your Relay Team

The Ideal Team Composition

For a competitive relay entry, the following profile split works well as a starting point:

• One strength athlete (Athlete 1 — SkiErg/Sled Push): high bench, good lat strength, handles heavy sled loads
• One power-endurance athlete (Athlete 2 — Sled Pull/BBJ): strong pull, can sustain high HR
• One aerobic specialist (Athlete 3 — Rowing/Farmer's Carry): best engine, solid technique under fatigue
• One CrossFit-style or functional fitness athlete (Athlete 4 — Sandbag Lunges/Wall Balls): metabolic durability, technique retention late in race

This is not a rigid formula. A four-person team where everyone is roughly equal in fitness can assign blocks experimentally — run the benchmarks and let the data decide.

Mixed-Sex Relay Teams

HYROX^® permits mixed relay teams. When male and female athletes are combined, weight standard matching becomes station-specific: whichever athlete takes the Sled Push block uses the load for their sex. Plan the assignments with this in mind, and confirm the specific event rules for mixed relay weight standards before registration, as these details occasionally vary.

For broader context on how co-ed pairings work in HYROX^® team formats, the HYROX^® Mixed Doubles guide covers the strategy principles that translate directly to relay planning.

Finding a Relay Team

If you do not have four athletes ready to commit, ROXBASE's partner-matching approach — used primarily for doubles — applies equally well to relay. Start with your immediate training group, then widen to gym members, then community boards. Shared training history matters more than raw fitness — you need people who will show up to three joint sessions in the months before the event.

The Find a HYROX^® Doubles Partner guide covers the evaluation framework, including the trial session protocol that reveals compatibility before you pay a race entry fee.

Race Day Preparation for Relay Teams

Arrive earlier than you think you need to. Walk the Roxzone together and identify the exact handoff location. Confirm which weight plates are pre-loaded and which your team needs to adjust. Brief every team member on the single verbal cue for a clean handoff.

Eat and hydrate according to each individual's own protocol — do not synchronise pre-race nutrition across the team. One athlete may be racing 45 minutes after another; their timing windows are different.

During the race: each athlete should warm up specifically for their block, not the generic team warm-up. Athlete 1 needs upper-body activation. Athlete 4 needs hip flexor and quad warm-up before a block of lunges and leg drive.

The HYROX^® Race Day Guide covers the full warm-up sequencing, kit logistics, and timing that apply to all race formats, including relay.

Frequently Asked Questions

Q: How many athletes are in a HYROX^® relay team? A HYROX^® relay team consists of exactly four athletes. Each athlete completes two consecutive stations and the two 1 km run segments that precede those stations. There is no three-person or five-person relay option in the standard HYROX^® format.

Q: Can relay athletes choose which two stations they do? The pairing is fixed by the sequential format — each athlete takes two adjacent stations in the eight-station order. What the team controls is which athlete does which block. That assignment decision, made before race day, is the primary strategic lever available to a relay team.

Q: Do all four relay athletes run at the same time? During the 1 km run segments, the full team runs together as a group. Only the active athlete works at the station; the other three wait in the transition zone. Each athlete runs a total of approximately 2 km across their two run segments.

Q: What happens if one athlete cannot finish their block mid-race? If a relay athlete is unable to complete their stations due to injury or withdrawal, the team must withdraw from the race. HYROX^® rules do not allow another team member to cover additional stations in place of an injured athlete. Build a contingency awareness into your pre-race briefing, particularly if any team member is carrying a pre-existing issue.

Q: Is HYROX^® relay a good format for beginners? Relay is one of the most accessible HYROX^® formats for new athletes because each person faces a lower total volume than individual or doubles racing. That said, lower volume does not mean lower intensity — each two-station block should be treated as a near-maximal effort within that block. Athletes who prepare specifically for their two stations will have a significantly better experience than those who show up undertrained.
