2026 update: ATHX has two U.S. events on its current calendar: Miami on October 10, 2026 at Miami Beach Convention Center and Houston on October 17, 2026 at NRG Park.
ATHX is one of the more interesting names in hybrid fitness right now because it sits between CrossFit and HYROX. It has running and rowing, but it also asks athletes to lift real weight. If you are already training CrossFit, chasing a HYROX time, or traveling for a fall event in Miami or Houston, this is the kind of format worth paying attention to.
This guide breaks down what ATHX is, how the October 2026 U.S. events are structured, and where to train if you are visiting Miami Beach or Houston for race week.
What Is ATHX?
ATHX is a 2.5-hour continuous fitness competition built across six zones. The official format includes warm-up, strength, refuel, endurance, recovery, and MetCon X. The idea is simple: test more than one kind of fitness in one event window.
The format is built around three core pillars: Strength, Endurance, and MetCon X. That makes it a useful bridge for athletes who like HYROX-style structure but still want heavier barbell work and functional strength to matter.
For 2026, ATHX lists Miami and Houston as U.S. stops, with individual and pairs divisions across ATHX Lite, ATHX, and ATHX Pro categories.
The Six Zones Explained
2026 U.S. ATHX Events
| Event | Date | Venue | Entry Types |
|---|---|---|---|
| ATHX Miami 2026 | October 10, 2026 | Miami Beach Convention Center | Individual and pairs |
| ATHX Houston 2026 | October 17, 2026 | NRG Park | Individual and pairs |
Both events list male, female, and mixed pairings, with heats running through the day. If you are traveling in, plan your gym drop-in around your heat time, sleep, and recovery. A hard WOD the day before ATHX is probably not the move.
ATHX Divisions
ATHX runs three main competitive tiers, available for individuals and pairs:
- Lite — Entry-level division for newer athletes or those testing the format for the first time. Reduced loads and shorter intervals.
- ATHX - The standard competitive tier. This is where many experienced gym-goers and hybrid athletes will fit.
- ATHX Pro - The heavier, more demanding division for serious competitors.
The 2026 workout page lists a 20-minute strength zone with strict press, back squat, and deadlift work; a 30-minute endurance zone with running and rowing; and a MetCon X zone with functional movements like ski-erg, sandbag carry, box jump overs, dumbbell lunges, and burpee broad jumps.
ATHX vs HYROX vs CrossFit — How Do They Compare?
| Format | Duration | Strength Emphasis | Endurance Emphasis | Structure |
|---|---|---|---|---|
| ATHX | 2.5 hours continuous | High - strict press, squat, deadlift | High - run and row intervals | 6 zones, fixed sequence |
| HYROX | 60–90 min avg | Moderate - functional movements | Very high - 8 x 1km runs | 8 stations, fixed sequence |
| CrossFit | Varies (10–60 min) | High - varied barbell and gymnastics | Moderate - workout dependent | Unknown workouts, changing each event |
The key distinction is that ATHX makes strength a central part of the score. HYROX rewards athletes who can run, transition, and grind through standardized stations. CrossFit rewards broad readiness across constantly varied workouts. ATHX borrows from both worlds but gives the barbell a clearer role.
The short version: HYROX rewards athletes who can run and grind. ATHX rewards athletes who can also move serious weight. CrossFit is the closest match to ATHX in terms of strength demands, which is why so many CrossFit athletes are showing up on the ATHX leaderboard.
Where to Train for ATHX in Miami
If you are traveling to Miami for ATHX, the event venue is at Miami Beach Convention Center, close to South Beach hotels and a short rideshare from downtown Miami. For training, look for gyms with barbells, rowers, ski-ergs, sandbags or sleds, and enough floor space to move under fatigue.
Start with WodFind's Miami CrossFit and HYROX gym directory. It includes 30 Miami-area gyms with addresses, phone numbers, and website links, including gyms close to downtown, Wynwood, South Miami, and Miami Beach.
- Race week: Do one light technique session early in the week, then keep the day before ATHX easy.
- Hotel choice: If you stay near Miami Beach Convention Center, check distance and traffic before booking a gym drop-in across the causeway.
- Training priority: Practice transitions between barbell work, running or rowing, and mixed-modal conditioning.
Where to Train for ATHX in Houston
ATHX Houston is listed for NRG Park, south of downtown and close to the Texas Medical Center. Houston is spread out, so training convenience depends heavily on where you stay. If you are near NRG, downtown, Montrose, or the Heights, choose a gym that keeps your travel time predictable.
Use WodFind's Houston CrossFit and HYROX gym directory to compare nearby options. The page includes Houston gyms with addresses and contact links so you can quickly check drop-in policies before race week.
- Near NRG: Prioritize a gym south or central Houston if you want a short rideshare before or after the event.
- Before race day: Keep your final session short: mobility, easy rowing, a few barbell warm-up sets, and light carries.
- After the event: If you are staying an extra day, look for open gym time instead of a hard class.
How to Choose an ATHX Training Gym
A good ATHX prep gym does not need to be branded as an ATHX facility. It needs the right equipment, coaching, and training culture. CrossFit gyms and HYROX-style functional fitness gyms are often a strong fit because they already combine strength, conditioning, and skill work.
- Barbells and racks: ATHX strength work rewards strict press, squat, and deadlift capacity.
- Cardio machines: Rowers and ski-ergs matter for event-specific prep.
- Loaded carries: Sandbags, dumbbells, kettlebells, and sleds help prepare your grip and trunk.
- Coaching: If you are new to heavy lifting under fatigue, choose a gym that coaches movement quality instead of just volume.
- Drop-in clarity: Traveling athletes should confirm class times, open gym rules, waiver requirements, and day-pass pricing before arriving.
Why ATHX Matters for Functional Fitness
HYROX has helped make hybrid racing mainstream, and ATHX is another sign that strength-and-engine events are becoming their own category. That is good news for gyms that already train people to lift, run, row, carry, and recover under pressure.
For athletes, ATHX offers another reason to train beyond aesthetics. For gym owners, it creates a content and programming opportunity: race prep classes, strength cycles, travel drop-ins, and community events around Miami and Houston.
