For the broader picture, read how many calories HYROX burns across four races.

How we measured

Key findings

  1. 01 — TOTALA 2:01:06 HYROX burned 1,441 kcal. That’s about 11.9 kcal per minute across the full race window — comparable to sustaining a hard tempo run for two hours straight.
  2. 02 — TOPS THE LISTWall Balls and Sled Pull tied at 115 kcal each — the costliest segments of the race.Both are also the two longest segments (11:28 and 10:01). Time on the floor wins.
  3. 03 — DURATION > INTENSITYThe five most expensive segments are also the five longest. Per-minute differences in intensity are smaller than per-segment differences in duration.

Further findings

  1. 04 — RUNS ≈ STATIONSRunning segments collectively burned 691 kcal; stations burned 632 kcal.Roxzone transitions added another 118 kcal. The metabolic split is roughly 48% running, 44% stations, 8% transitions.
  2. 05 — CHEAPESTFarmers Carry burned just 29 kcal — by far the cheapest segment. At 2:29 it’s also the shortest. Per-minute burn rate was competitive; the total is small because the segment is brief.

Why this question matters more than runners think

HYROX athletes obsess over splits. The 7:01 first-run, the 5:11 SkiErg, the 11:28 Wall Balls — these are the numbers we share, screenshot, and post-mortem. But splits only tell you what happened. They don’t tell you why minute 95 felt the way it did, or why some segments leave you hollowed out for the next run while others don’t.

Calorie burn is one of the better answers. It’s a single number that aggregates duration, intensity, and muscle-mass engaged — the closest thing we have to a “total cost” figure for each part of the race. And in this data, it tells a different story than the splits do.

Stations cluster at the top of the list because they’re long. Runs spread through the middle. The shortest segment, Farmers Carry, sits at the bottom — not because it was easy but because 2 minutes 29 seconds wasn’t long enough to accumulate.

What the data actually shows

The biggest surprise isn’t the hardest segment

If I’d been asked beforehand to predict which segment would top the calorie list, I’d have said one of the running segments. They had the highest heart rates — R3 and R7 both averaged 178 bpm — and they felt the most all-out. I would have been wrong.

The costliest segments were Wall Balls and Sled Pull, tied at 115 kcal each. Wall Balls is the obvious one with hindsight: 100 reps of squat-to-throw is a full-body grind. Sled Pull is less obvious. It ended with the lowest heart rate of any station (158 bpm), it has built-in rest intervals (you walk back between pulls), and its per-minute calorie burn was lower than several of the runs.

What both segments share is duration. Wall Balls took 11:28. Sled Pull took 10:01. The next three on the calorie list — Burpee Broad Jump (104 kcal), Run 8 (104), Run 3 (103) — are all in the 7–8 minute range. The five most expensive segments are also the five longest.The data is dense with this finding: in HYROX, cost is duration-driven.

The Sled Pull paradox

Sled Pull deserves a second look. It posted the lowest finishing HR of any station. One of the more comfortable per-minute calorie rates. And yet: highest total calorie burn, tied with Wall Balls.

The explanation is in the structure of the segment. You pull the sled in stages — short bursts followed by walks back to the start. The walks don’t actually rest you; heart rate stays elevated and you’re still under tension. But they stop the segment from feeling like a continuous burn. You finish Sled Pull thinking you’ve recovered.

The next run says otherwise. The transition from Sled Pull to Run 4 produced a 21 bpm jump (157 → 178) — the biggest cardiovascular spike of the entire race. Sled Pull hadn’t been a rest; it had been a low-grade, sustained tax on the system. The calorie figure captures that more accurately than the average HR does.

Are HYROX runs or stations more demanding?

This is an old debate in HYROX coaching circles, with strong opinions on both sides. The data here is unambiguous and slightly anticlimactic: they’re roughly equal.

The eight running segments collectively burned 691 kcal. The eight workout stations burned 632. The remaining 118 kcal came from the roxzone — the time spent moving between segments. The metabolic split was approximately 48% running, 44% stations, 8% transitions.

That’s a 50/50 race by energy cost, give or take a few per cent in either direction. It supports HYROX’s own framing of the sport as a true hybrid event rather than a running race with stations attached. From a training standpoint, it suggests that strength and station-specific work shouldn’t be treated as secondary preparation. The stations are exactly half the race, energetically.

What this means for race day

Two practical implications.

The long segments matter most. If you’re going to find time, find it on the floor. Wall Balls at 11:28 represents 10% of the entire race; Sled Pull at 10:01 is another 8%. Together that’s 18% of race time and 16% of total calorie burn. Getting faster at those two will drop your finish time more than equivalent improvements elsewhere.

Fuelling deserves more thought than most amateurs give it. 1,441 kcal of active energy is substantial — more than the daily active burn for many people, packed into two hours. Going in glycogen-depleted invites the wheels coming off around minute 85. Most HYROX athletes carb-load for a marathon-style race; few treat HYROX with the same respect. They should.

What these numbers aren’t

Apple Watch active_energy is an estimate, not a measurement. Validation studies against indirect calorimetry put it within about ±10–15% for cardiovascular activity, with consistency typically poorer for strength work. The absolute total here — 1,441 kcal — could plausibly land anywhere between roughly 1,200 and 1,650 on a metabolic cart.

Internal consistency within a single athlete’s data is much better than cross-athlete accuracy. The relative ranking of segments — which ones cost more or less — is solid. The 50/50 runs-vs-stations split holds even at 15% measurement noise on either side. The Sled Pull paradox holds. The duration-wins finding holds.

Treat these numbers as a credible relative comparison between segments of one race, not as a precise absolute. And don’t use my body’s data as a stand-in for yours: heavier athletes burn more per segment; faster athletes burn less in total; fitter athletes burn more efficiently per heartbeat.

Frequently asked questions

How many calories does a HYROX race burn?

For this 2:01:06 race, the Apple Watch recorded 1,441 kcal of active energy across all 16 segments — an average of about 11.9 kcal per minute. That’s comparable to a sustained hard tempo run kept up for two hours. Individual burn varies with body weight, finishing time, and effort. A faster 90-minute finish on the same body would burn less because total time-on-floor is shorter; a slower 2:30 finish would burn more.

Which HYROX station burns the most calories?

In this race, Wall Balls and Sled Pull tied as the costliest segments at 115 kcal each. They’re also the two longest segments in the race — Wall Balls at 11:28 and Sled Pull at 10:01. The pattern holds across the data: duration drives total cost more than intensity does. Sled Pull is particularly notable because it had the lowest average heart rate of any station (158 bpm) yet topped the calorie chart — the long, technical, stop-start nature kept HR moderate but total time-under-load high.

Do HYROX runs or stations burn more calories?

Approximately equal. In this race, the eight running segments collectively burned 691 kcal and the eight workout stations burned 632 kcal. Roxzone transitions accounted for the remaining ~118 kcal. The metabolic split was roughly 48% running, 44% stations, and 8% transitions. HYROX is genuinely a hybrid race by energy cost, not a “running race with some stations attached.”

How was this calorie data measured?

Active energy was captured on an Apple Watch during a Mixed Cardio workout session and exported as JSON via the Health Auto Export iOS app. Apple’s active_energy metric estimates expenditure above resting metabolic rate, computed from heart rate and motion data. It’s an estimate, not a metabolic-cart measurement — absolute values can vary between athletes by 10–15% — but the metric is internally consistent within a single athlete’s data, which makes it useful for comparing segments within one race.

Every station. Every beat.

Methodology & data provenance

Active energy was captured on an Apple Watch during a Mixed Cardio workout (started 09:50:10 IST, ended 11:51:38 IST on 12 April 2026), exported via the Health Auto Export iOS app as JSON. Apple’s active_energy metric estimates expenditure above resting metabolic rate, computed from heart rate and motion sensors. The Watch reports values in kilojoules; figures here are converted to kilocalories at 1 kcal = 4.184 kJ.

Per-segment totals are computed by summing active_energy samples that fall within each segment’s start and end time, using durations taken from the official HYROX race results (bib 95039, HYROX Bengaluru 2026, Sunday division). The 10:12 of total roxzone time is distributed equally as ~41 seconds between each of the 15 segment transitions.
