What Is ATHX? The Hybrid Fitness Competition Explained (Format & Scoring)

ATHX is a 2.5-hour continuous hybrid-fitness competition that tests three distinct athletic qualities in a single event: maximal strength, aerobic endurance, and metabolic conditioning. Powered by adidas and staged across six zones, it packs a near-limit barbell session, a 22-minute run-and-row time trial, and a multi-movement chipper into one competition day.

Only three of those six zones count toward your score. That is the part most newcomers miss. The Warm-Up, Refuel break, and Recovery zones are real—and useful—but they do not move the needle on the leaderboard. Your placing comes entirely from the Strength, Endurance, and MetCon X zones. Understanding what each one demands, and how the scores combine, is where ATHX strategy starts.

The Three Scored Zones

The non-scored zones (30-min Warm-Up, 10-min Refuel, 30-min Recovery) account for an hour of the 2.5-hour event and bracket the scored work. The three that matter:

Zone	Cap	What you score
Strength	20 min	Total weight lifted
Endurance	22 min	Total distance (m)
MetCon X	25 min	Time to complete

Strength — 20 Minutes, Three Lifts

The Strength zone runs a rolling ladder: 20 minutes split into three windows, each assigned a different barbell movement.

Window	Lift
0–6 min	1RM strict press
6–12 min	3RM back squat
12–20 min	5RM deadlift

Movement standards matter. The strict press begins in the rack, is walked to front-rack position, and requires no dip or leg drive—it is a strict overhead press, not a push press. The back squat goes to below parallel (hip crease below the top of the knee). The deadlift starts from the ground on every rep, hands outside the knees; sumo stance is not allowed. There is a maximum five-second pause between reps on the deadlift.

Your zone score is the sum of your heaviest bar per lift—press 1RM + squat 3RM load + deadlift 5RM load. More on why the distinction between "loads" and "tonnage" matters below.

Endurance — 22 Minutes, Run Then Row

The Endurance zone is a 22-minute time trial with one task: alternate between running and rowing, accumulating as much combined distance as possible before the cap.

Individuals (and Team athlete A) start on the run, carrying a baton. The swap happens at fixed thresholds that apply equally to both the run and row legs:

Division	Swap distance
LITE	500 m (2 laps)
ATHX / standard	750 m (3 laps)
PRO	1,000 m (4 laps)

A standard-division athlete runs 750 m, rows 750 m, runs again, and so on until time expires. Your score is the total combined metres across both modalities.

MetCon X — 25 Minutes, a Chipper for Time

MetCon X is a capped chipper: complete the prescribed stations as fast as possible, with a hard 25-minute cap. Your score is your finishing time. Athletes who do not finish before the cap are scored at the cap—so every remaining rep costs you on the leaderboard.

The verified individual (standard division) stations and loads for 2026:

Station	Individual load / target
Ski-erg	M 45 cal · F 30 cal
30× alternating DB ground-to-overhead	M 20 kg · F 12.5 kg
30 m sandbag carry	M 50 kg · F 30 kg
30 box jump-overs	M 24″ · F 20″
DB walking lunges	rep count not confirmed—see note
Burpee broad jumps	rep count not confirmed—see note

A note on the final two stations: the exact rep counts and distances for the walking lunges and burpee broad jumps are not independently verified for the individual division at time of writing. Pull the current individual scheme directly from athxgames.com (Workouts → 2026) before programming them precisely into training.

PRO athletes lift heavier throughout (dual-DB GTOH at M 22.5 kg / F 15 kg, sandbag M 70 kg / F 40 kg, box M 30″ / F 24″). LITE athletes use lighter loads (single-arm GTOH at M 15 kg / F 7.5 kg).

How ATHX Scoring Actually Works

This is the section nobody online explains cleanly—and where the biggest misconceptions live.

Rank-Sum: Lowest Points Wins

ATHX does not have a single performance metric you can directly optimise. Instead, each scored zone produces a placing relative to everyone else in your division. Those three placings are summed into a Points total. Lowest total wins.

The leaderboard makes this concrete. A competitor's row might look like this:

Strength	Endurance	MetCon X	Points
10 (295 kg)	3 (4.844 km)	3 (09:24)	16

That athlete finished 10th in Strength, 3rd in Endurance, and 3rd in MetCon X—leaderboard Points of 16. A competitor at 12 Points finished higher; one at 20 Points finished lower.

The practical implication: you do not need to win any single zone to win the event. A consistent all-rounder who places 4th–5th in every zone (≈ 12–15 Points) will beat a specialist who dominates Strength but collapses in MetCon X.

Worth noting: the rank-sum structure is strongly corroborated by the arithmetic visible across the leaderboard, but the official ATHX site does not state the aggregation formula verbatim. The Points column behaves exactly as described; that is the working model.

Tiebreak: The official tiebreak rule for equal Points is not publicly published at the time of writing. Do not assume any particular tiebreak applies—check the official competition guide before a result depends on it.

Strength Score: Loads, Not Tonnage

One of the most persistent misconceptions about Strength scoring: athletes assume the deadlift is scored by tonnage—load × reps—so pulling 5 × 120 kg is worth 600 kg, not 120 kg.

That is not how it works.

Your Strength score is the sum of the heaviest bar in each lift. The deadlift contributes its 5RM load—not load × 5. The squat contributes its 3RM load—not load × 3. This means adding 5 kg to your deadlift max is worth exactly the same as adding 5 kg to your strict press max, regardless of how many reps each lift requires.

The strategic implication: do not sacrifice strict press or squat potential to squeeze extra kilograms onto the deadlift. The exchange rate is 1:1 across all three lifts.

Divisions and Gender

ATHX currently runs four competition formats:

• LITE — reduced loads and shorter Endurance swap distances; accessible entry point
• ATHX (standard / individual) — the main individual format
• PRO — heavier loads, longer swap distances, higher MetCon X standards
• Pairs / Teams — two-athlete format with split responsibilities (one athlete runs, the other rows during Endurance)

Within each division, gender splits exist for loads and ski-erg calorie targets. Gender is not a separate division—it is a load and standard modifier within the division you enter. Any calculator or programming tool needs both a division and a gender to produce accurate targets.

Age-group division rules and full pairs/team rep schemes were not publicly confirmed in the research for this post. The official competition guide at athxgames.com is the definitive source for those details.

What Changed from 2025 to 2026

ATHX updates its format annually. If you find information online without a season label, treat it with caution—the 2025 and 2026 formats are materially different.

Zone	2025	2026
Strength	2 lifts: 6-min back squat 5RM + 6-min strict press 10RM	3 lifts: press 1RM · squat 3RM · deadlift 5RM
Endurance	Run + bike (12-min run, 2-min rest, 12-min bike)	Run + row (22-min alternating)

The 2026 Strength zone added the deadlift and shifted the press from a 10-rep max to a true 1RM—dramatically changing the strength profile that ATHX preparation demands. The swap from bike to rowing in Endurance similarly shifts the training emphasis, since rowing loads the posterior chain in a way a stationary bike does not.

Everything above describes 2026 format only.

ATHX vs HYROX: What's the Difference?

Both events draw heavily from the hybrid fitness community, but the formats solve different problems.

HYROX is a fixed, head-to-head race: run 1 km, complete a functional station, repeat eight times. The course is the same for every competitor in the same division. You are racing the clock across 17 standardised segments. The winner has the fastest time.

ATHX is a three-zone competition that tests near-maximal strength, maximum-distance endurance, and a timed chipper—scored independently and combined via rank-sum. There is no fixed race sequence. You are competing for zone placings rather than an absolute time.

The training gap is significant. HYROX rewards athletes who sustain aerobic pace across a long, repeated run-station sequence. ATHX rewards athletes who can peak for heavy barbell work, rack up metres on run-and-row, and drive through a loaded chipper—three distinct energy system demands on a single day.

If you are training for HYROX, the HYROX Workout Generator and Pacing Calculator are built for those race demands. The pacing strategy guide walks through the full HYROX format in depth.

ATHX Is Coming to the US

ATHX's US debut is the ATHX Invitational: Miami Beach, March 21–22, 2026—the competition's first US event, staged in partnership with Breakwater Hospitality Group and powered by adidas. For anyone considering competing in 2026, that is the event to watch.

Where to Start

ATHX rewards athletes who know their numbers across all three scored zones. The first step is building baseline benchmarks: what can you lift across the three Strength movements under a 20-minute time constraint, how far can you cover in 22 minutes of alternating run and row, and where does your MetCon X pacing land relative to the prescribed loads?

Once you have those baselines, programming becomes clear: attack the zone where your placing costs you the most Points, and keep the others from slipping.
