STRONGER THAN YESTERDAY. EVERY SINGLE DAY.
Relentless Hybrid is an official HYROX Training Club and Deadly Dozen affiliated facility, built for one purpose — to get you to the start line ready and the finish line faster.
Purpose-built programming, dedicated coaching and a facility designed from the ground up for the person who trains with race day in mind or just a better everyday life.

More Than a Race. A Lifestyle.
What Is HYROX
HYROX is the fastest growing competitive fitness format in the world. One race. Eight functional fitness stations. Eight one kilometre runs in between. It is the same race format every time, which means every session you train is direct preparation for race day.
It is built for everyone. First timers and elite athletes compete in the same event under the same format, with divisions that meet you where you are. The goal is simple. Finish stronger than you started and faster than you were before.
No two athletes arrive at the same starting point and no two race journeys look the same. Every session at Relentless Hybrid is built around your goal, whether that is finishing your first race, hitting a personal best or chasing a podium.
Why HYROX Works — And Why It Works Here.
It is structured.
Every session at Relentless Hybrid is designed around the HYROX race format. You are not just getting fit. You are building the specific fitness that race day demands. Nothing wasted. Everything intentional.
It is measurable.
HYROX gives you something most training does not. A finish line with a time on it. Every simulation, every session, every rep is trackable progress toward a result you can actually see. That clarity changes how you train.
It is comparable.
The format never changes and neither do the standards, so your time in Cape Town means the same thing as a time posted anywhere else in the world. One global leaderboard, one honest measure of where you stand.
HYROX is the global fitness race for everybody, where each event follows the exact same race format, allowing for a comparable global leaderboard for all athletes.
The race starts with a 1km run, followed by one functional workout, repeated eight times. All global races take place in large indoor venues, creating a stadium atmosphere and a race experience unlike anything else on the calendar.
Divisions run from Open through Pro, plus Doubles and Relay, so you can take it on solo or share the load with a partner or a team.
The Eight Stations
Every station is preceded by a one kilometre run. Eight of each, in order, no rest between them.
Weights, sled loads and wall ball targets are set by HYROX per division. Always check the official race information for your category before you enter.
Where It Lives On Our Timetable
How We Train It At Relentless Hybrid
As an officially designated HYROX Training Club we run programming built around the race itself, not around a generic conditioning template. Our floor holds the sleds, the ergs, the bags and the running lanes, which means you train the actual race rather than an approximation of it.
Sessions are built around three things the race punishes hardest, and every one of them is coached and scaled on the day.
Compromised Running
Running with tired legs is the whole race. We pair run intervals directly with station work so your pace holds after the sled instead of falling apart on the way out of it.
Station Specific Work
Sled push and pull mechanics, erg pacing, lunge efficiency, wall ball rhythm. Each station is drilled on its own so nothing on race day is the first time you have met it.
Race Simulations
Full and partial run throughs against the clock. This is where pacing strategy, transitions and fuelling get tested properly, well before you are standing on a start line.
No race entry required and no experience needed. Come in for the training, decide about the start line later.
Twelve Journeys. Twelve Labours.
What Is Deadly Dozen
Deadly Dozen is a global fitness race run on an athletics track. Twelve 400m runs, called Journeys. Twelve strength stations, called Labours. Back to back, no rest between them, until all twelve are behind you.
The Labours use nothing more than a kettlebell, a dumbbell, a weight plate and your own bodyweight. There is no technical barrier and no specialist kit, which is exactly why it is described as one of the hardest and most accessible races in the world. Anyone can start it. Very few master it.
It is open to everyone from eighteen up. Race it solo, in a pair, or as a relay team of four. The format is identical wherever it is run, so your time sits on a global leaderboard next to every other athlete who has taken it on.
Why Deadly Dozen Works — And Why It Works Here.
It is honest.
Twelve rounds of the same decision. Run hard, work hard, go again. Nothing technical stands between you and the finish and there is nowhere in the format to hide. What you built in training is exactly what shows up on the track.
It is scalable by design.
Every Labour loads up or dials back without taking you out of the race. A modified rep still finishes the race rather than ending it. That is why the same session works for a first timer and a podium chaser standing side by side.
It carries across.
Running under fatigue, carries, presses, squats, grip, engine. The work that gets you through twelve Labours is the same work that gets you through a HYROX race. Train one and you are already building the other.
The pattern never changes. A 400m Journey around the track, then a Labour. Twelve times through. Roughly 4.8km of running with twelve strength stations stacked in between, all of it in full view of the crowd.
Race day runs as a full day out. Spectator stands, a vendor village, recovery zones, families on the grass. It is a fitness festival with a race at the centre of it, deliberately built so first timers and seasoned racers line up on the same track under the same rules.
Beyond the track race there are indoor and variation formats. Deadly Sprint runs shorter and faster, and Row, Ski and Cycle versions swap the running for machine work. Same method, different door in.
The Twelve Labours
Every Labour is preceded by a 400m Journey around the track. Twelve of each, in order, no rest between them.
Reps, distances and loads are set by Deadly Dozen per race and per division. Always check the official race pack before you line up.
Not Just A Race. A Method.
The Deadly Dozen Triad
Deadly Dozen is a training methodology first and a race second. The method splits fitness into three pillars, and the race is simply the test that exposes which one you have been neglecting. Train all three and you beat the race. Train one and it beats you.
Strength
Heavier resistance work at lower volume. The capacity to move real load with control, and to keep that control when your legs are cooked and your grip is going. Strength is what stops the Labours falling apart in the back half.
Labour Fitness
Circuit work built from the Labours themselves, run at high volume for reps or for time. This is the pillar most people underestimate, and it is where grip and upper body endurance are won or lost across twelve stations.
Journey Fitness
The aerobic engine. Longer steady work and shorter interval work, on foot or on a machine. The goal is not just to survive the run. It is to arrive at each Labour able to actually work when you get there.
The Dozenal System
Every rep count and distance in Deadly Dozen is built on the number twelve. That is not a gimmick. It means any Labour can be moved up or down by twenty five, fifty or seventy five percent and still land on clean, whole numbers.
That single design choice is what makes one session work for a whole room. Same movement, same clock, same standard. Different gear.
Where It Lives On Our Timetable
How We Train It At Relentless Hybrid
As a Deadly Dozen affiliated facility, the official programming comes to us and we run it inside our HIIT classes. Same floor, same coaches, same timetable you already train on. You do not need a separate membership and you do not need to be entered for a race to train it.
Our HIIT sessions follow the Triad rather than chasing random hard work. Across the week the three pillars are covered deliberately, so you build a complete engine instead of hammering the one thing you are already good at.
Strength Days
Loaded resistance work through the movement patterns the Labours are built from. Squat, hinge, carry, press. Heavier, lower reps, coached technique under load.
Labour Days
Circuit sessions built from the twelve Labours at race volume. Kettlebell, dumbbell, plate and bodyweight only. This is where grip, pacing and mental staying power get built.
Journey Days
Running and machine intervals paired with Labour blocks. Long steady efforts to build the base, sharper intervals to build the top end, and full race simulations closer to an event.
Every session is scaled on the day. No experience needed, no race entry required, and you never train without a coach watching.
