HYROX wall balls: rules, the digital target, 100-rep pacing

HYROX wall balls are 100 reps in every division for 2026/27: a 4 kg ball for Women, 6 kg for Men and Women Pro, and 9 kg for Men Pro, thrown to a 2.70 m target for women and 3.00 m for men¹. Every rep is a squat with your hips below your knees, then a two-handed throw that hits the target. For pacing, plan your sets and keep the rests short and fixed, because rest is the part you control and the part that swings the total.

It's the last station, straight after the eighth run. In Brandt's simulated race, wall balls produced the highest heart rate, lactate and effort ratings of the whole event².

The standard, rep by rep#

That's 8 ft 10 in and 9 ft 10 in if you're setting up a target at home. All from section 8.8 of the Singles rulebook¹.

What makes a valid rep¹:

• Start standing tall, hips and knees extended, ball in both hands. You can't scoop it off the floor and throw it in one go.
• Full squat: hips below knees at the bottom.
• Throw with both hands and hit your target inside the strike zone. Women hit the women's target, men the men's.
• Catch it or let it drop. Both are fine. What isn't: catching it after a bounce and going straight into the next rep.
• No warnings. Unlike stations 1 to 7, wall balls don't get a warning first. It's a rep or a no-rep.

Smaller rules worth knowing: you can take your shoes off at your target (they go under the rig, and you carry them to the finish). Powdered chalk at the wall balls is a 2-minute penalty. Leaving before 100 valid reps is a disqualification¹.

If you've heard 75 for Women Open#

Some guides still say Women Open is 75 reps. A 2024 Red Bull guide does³. The 2026/27 Singles and Doubles rulebooks both say 100 reps with the 4 kg ball for Women¹⁴. Train for 100.

The digital target#

Some events use digital screens on the rig. Here's how the rulebook says they work¹:

• The screen shows your rep count and flags no-reps. It splits no-reps into two kinds: movement faults (not meeting the standard, such as squat depth, or breaking the movement pattern) and target faults (missing the target or hitting the wrong one).
• The screen doesn't decide whether a rep counts. A rep is valid only when the movement standard is met and the ball properly hits the correct physical target. The physical target and the judge's confirmation are the official standard.
• After 100 valid reps the screen turns green and shows GO. That's your signal to head to the finish.
• Where there's no digital target, you can only go to the finish once your judge confirms 100 valid reps.

The judge can also put a squat depth box under you if your depth is in doubt. You can't ask for one, and you can't rest on it¹.

In practice that means you can't argue with the screen, but you also can't lean on it. If the depth is borderline, go deeper. A no-rep costs a full rep, and you don't get a warning.

Doubles wall balls#

Same 100 reps, shared between the two of you in whatever split you like. Doubles Women use 4 kg; Women Pro, Men and Mixed use 6 kg; Men Pro use 9 kg; and each partner throws to the target for their own sex⁴. The resting partner stays in the marked area under the rig. You pass the ball by dropping it or handing it over. A "flying" handover, where one throws and the other catches it into their squat, is a no-rep⁴.

Technique that saves reps#

None of this comes from a study. These are the common coaching cues, and each one is about not wasting a rep or the energy for the next one.

• Stand at a distance you can repeat. Close enough that a good throw comes straight back to your hands, far enough that the ball doesn't clip the rig on the way up. Find it in the first couple of reps and don't drift.
• Throw with your legs. The drive out of the squat should do most of the work. If your shoulders give out before your legs do, your arms are doing too much.
• Catch high and ride it down. Catching the ball at face height and sinking straight into the next squat keeps the rhythm. Waiting for it at chest height and then squatting is a pause on every rep.
• Hit depth on purpose. The standard is hips below knees, and a depth fault shows up on the screen as a movement fault. Going a little deeper than you think you need is cheaper than a no-rep.

Pacing 100 reps: the arithmetic#

The time on 100 wall balls is just two numbers: how long one rep takes, and how much you rest. You can't change your rep speed much on race day. The rest is entirely up to you.

I'll use my own training numbers. On 14 July I did 25 wall balls at 6 kg in 65 seconds straight off a 1 km run, which is 2.6 seconds per rep. A week later it was 30 in 80 seconds, about 2.7. Call it 2.6 seconds per rep when fresh-ish.

At 2.6 seconds a rep, 100 reps of pure work is 4:20. Then add the rest:

100 wall balls at 2.6 s per rep: how rest changes the total

	Value (min)
Unbroken	4.33
4 x 25, 15 s	5.08
5 x 20, 15 s	5.33
10 x 10, 10 s	5.83
10 x 10, 20 s	7.33

Worked example: 100 reps x 2.6 s plus the rests listed. Rep speed from Ken's logged training sets (25 reps in 65 s, 14 July 2026). Arithmetic, not race data.

Look at the last two rows. Same sets of ten, and the only change is 10 extra seconds per rest. That's 1:30 on the clock, more than the gap between going unbroken and going in fours. And reps slow down when you're tired: at 3.0 seconds a rep, the 10 x 10 plan with 10-second rests becomes 6:30.

So the useful plan is the one with the biggest sets you can repeat without long stalls, and rests you actually time. The table shows what an untimed rest that drifts from 10 to 20 seconds costs. Count the rest in breaths if you can't watch a clock, and start the next set when the count runs out, not when you feel ready.

The same logic says a no-rep is expensive. Each one costs another full rep, about 2.6 seconds, plus whatever it does to your rhythm.

Arriving at the wall balls#

My last run in Bangkok, from the final Roxzone exit to the wall ball station, took 4:54, nearly a minute slower than my middle runs. Then 100 wall balls took 6:34, ranked 803rd of 3,254 men, which HYRESULT puts in the best 51.8% of its all-seasons results⁵. Against my own training rep speed, that's a bit over two minutes on top of the 4:20 of pure throwing, spent on rests, slower reps and any no-reps. The timing can't tell me how that two minutes split, so I won't guess.

For context, hybridAF's own reference for wall balls in a roughly 1:15 to 1:25 race is 5:00. That's our approximation, not an official number. My 6:34 sits well behind it, in a race I finished in 1:13:38. The pacing table above shows where that kind of time can hide: in the rests.

At the very top, wall balls have improved more than any other station. Among the top 100 Pro men, the wall ball time fell from 6:06 in season 1 to 3:55 in season 7⁶. Those are Pro athletes with 9 kg balls, so it's not a target for anyone in Open, but it shows how far this station has moved with training at the top level.

Two things help the transition. First, run 8 isn't the place to bank time. A hard run 8 that costs you three extra breaks at the rig is a bad trade. The run pacing guide and the compromised running guide both cover it. Second, practise wall balls after running, not fresh. Sets of 25 to 30 straight off a 1 km run, like the sessions above, tell you your real rep speed and the set size you can actually hold.

Building up to 100#

If 100 reps in one go is new to you, build it the way you'd build any volume. Start with sets you can finish cleanly, add total reps across the weeks, and only then cut the rests. Do at least some of it at the right target height with the right ball, because a different height changes the throw. And do most of it tired: after a run, or at the end of a session, since that's when you'll meet it in the race.
