Deadly Dozen Race Guide: What It Is, How It Works and How to Prepare
The Deadly Dozen is a hybrid fitness race held on an athletics track, combining 12 x 400m runs (called Journeys) with 12 functional exercise stations (called Labours), all completed in sequence with no rest between them. It is open to all adults aged 18 and over, scalable for beginners, and requires nothing more than a kettlebell, dumbbell, and weight plate to train for.
If you’ve been seeing location-specific searches popping up this summer, Kevelaer, Klagenfurt, Davos, Vancouver, and Crystal Palace for the World Championships, there’s a reason for that. The Deadly Dozen is growing at a rate that is turning heads across the hybrid fitness world, and 2026 is shaping up to be its biggest year yet.
This guide covers everything: what the race involves, the 12 Labours in full, how it compares to HYROX, realistic finish times, and precisely how to prepare so you arrive at the start line ready to race it well.
Key Takeaways
- The Deadly Dozen combines 12 x 400m runs with 12 functional exercise stations on an athletics track, totalling roughly 4.8km of running.
- The 12 Labours use only a kettlebell, dumbbell, and weight plate, meaning the movements are trainable anywhere with basic kit.
- Scaling is built into the format: athletes who need to modify a Labour complete the race with an “(s)” next to their time, not a DNF.
- Entry categories include Solo, Pairs, and Relay (teams of four), with mixed pairs completing at male weights.
- Competitive athletes typically finish in under 90 minutes; the broader field varies based on Labour pace and conditioning.
- The 2026 calendar includes international events in Germany, Austria, Switzerland, and Canada, plus the World Championships at Crystal Palace, London on 5, 6 September 2026, with a £120,000 prize pot.
- Hybrid athletes already training for HYROX adapt quickly to Deadly Dozen, as running fitness and functional strength transfer directly.
What Is the Deadly Dozen Race?
The Deadly Dozen was founded by Jason Curtis and the Institute of Fitness Racing as an athletics-track-based fitness race built around what its creators call the dozenal system: every element of the race is rooted in the number 12.
The format is deceptively simple. You run a 400m lap of the track (a Journey), then complete a functional exercise station on the grass infield (a Labour), then run another lap, complete another Labour, and repeat until you have done 12 of each. That’s 4.8km of running and 12 exercise stations, all completed in order, with no formal rest periods.
What makes Deadly Dozen stand out from most hybrid fitness events is the equipment philosophy. There is no ski erg, no sled, no rowing machine. Every Labour uses a kettlebell, dumbbell, weight plate, or bodyweight only. The movements are the same ones you’d train in any well-equipped gym or even a decent home setup. That accessibility is deliberate.
The race takes place on a standard athletics track, with Labours set up on the infield grass. The atmosphere is closer to a community sports day than a warehouse fitness event: spectators can watch from the stands, athletes start in small waves of two to four, and the open-air setting gives it a completely different feel to indoor arena events.
Who Is It For?
The Deadly Dozen is open to all adults aged 18 and over. You do not need to be an experienced athlete to enter, and the format includes a formal scaling system so that beginners can complete the race without being forced to withdraw.
Whether you’re a seasoned HYROX racer looking for your next challenge, a runner who wants to add functional fitness to your race calendar, or a gym-goer who has been watching hybrid fitness grow and wants to try it for the first time, the Deadly Dozen is built to accommodate you.
The 12 Labours: What You Will Actually Face
The Labours split evenly into two types that alternate through the race: six Distance Labours, where you cover a set distance carrying or moving a weight, and six Rep Labours, where you complete a fixed number of repetitions.
A judge is stationed at every Labour. Athletes receive up to three warnings before their result is marked as scaled (“(s)”). The standards are firm but the intent is clear: complete the movement properly, and you’ll have no issue.
Below is the full Labour list in official race order, with the weight standards published in the Deadly Dozen rulebook (they differ by gender). Confirm the current standards for your specific event and division on the Deadly Dozen official site before race day.
| # | Labour | Type | Amount | Weight (Male / Female) |
|---|---|---|---|---|
| 1 | Kettlebell Farmer’s Carry | Distance | 240m | 2 x 24kg / 2 x 16kg |
| 2 | Kettlebell Deadlift | Reps | 60 | 32kg / 24kg |
| 3 | Dumbbell Lunge | Distance | 60m | 2 x 12.5kg / 2 x 7.5kg |
| 4 | Dumbbell Snatch (alternating) | Reps | 60 | 15kg / 9kg |
| 5 | Burpee Broad Jump | Distance | 60m | Bodyweight |
| 6 | Kettlebell Goblet Squat | Reps | 60 | 16kg / 12kg |
| 7 | Weight Plate Front Carry | Distance | 240m | 25kg / 20kg |
| 8 | Dumbbell Push Press | Reps | 60 | 2 x 12.5kg / 2 x 6kg |
| 9 | Bear Crawl | Distance | 120m | Bodyweight |
| 10 | Weight Plate Clean and Press | Reps | 60 | 15kg / 10kg |
| 11 | Weight Plate Overhead Carry | Distance | 180m | 15kg / 10kg |
| 12 | Dumbbell Devil Press | Reps | 20 | 2 x 10kg / 2 x 5kg |
That works out to 4,800m of running across the Journeys, roughly 900m of loaded carries and movement across the Distance Labours, and 320 total reps across the Rep Labours.
The official Deadly Dozen Labour Techniques and Tips page is worth reading before your first race. The coaching notes on the Farmer’s Carry are particularly useful: a light jog rather than a full sprint reduces kettlebell swing and saves grip for later stations more than almost any other single tactical adjustment.
One tip that comes up repeatedly in race reports: grip endurance is the hidden limiter in the back half of the race. The three loaded carries (Farmer’s Carry, Front Carry, and Overhead Carry) plus the Deadlift and the Snatch place the heaviest demand on hand and forearm strength. If you train nothing else specifically for the Deadly Dozen race, train your grip.
Race Formats and Entry Categories
Track Race vs. Gym Races
The Track Race is the flagship Deadly Dozen format: 12 Journeys, 12 Labours, athletics track, full format. This is what most articles and race guides are referring to when they discuss the event.
Deadly Dozen also offers Gym Race formats, Deadly Strong, Deadly ERG, and Deadly Mile, which are shorter or modified versions designed for gym-based events or time-limited formats. If you’re new to the race series, the Track Race is the one to aim for.
Solo, Pairs, and Relay
| Category | How It Works | Age Grading |
|---|---|---|
| Solo | Individual athlete; completes all 12 Labours and 12 Journeys | Own age |
| Pairs | Two athletes; share Labours and Journeys (partner waits at station) | Average of both ages |
| Relay | Team of four; athletes rotate across stations and runs | Average of all four |
Important for Pairs: Mixed pairs (one male, one female) race at male weights. Factor this into your training if you’re entering as a mixed pair.
Wave Format and Seeding
Athletes start in waves of two to four every five to six minutes. There is no mass start, which keeps the Labour stations from bottlenecking and gives the race a controlled, focused atmosphere rather than a chaotic festival feel.
Before the race, athletes complete a Seeding Labour: a short pre-event assessment that determines your wave placement. Practising a Seeding Labour before race day is worth doing if you can, as it gives you a realistic baseline for your pace and helps you avoid being placed in a wave that starts too fast or too slow for your current fitness level.
Scaling: What “(s)” Means
If an athlete cannot complete a Labour to the required standard after three warnings, the rep or distance is adjusted and the result is marked with an “(s)” for scaled. This does not mean disqualification. You continue the race, complete every remaining Labour and Journey, and receive a finish time.
For beginners, this is a genuinely meaningful feature. It means the Deadly Dozen does not force athletes to either perform a movement incorrectly at risk of injury or abandon the race entirely. You scale, you finish, and you come back next time stronger.
Deadly Dozen vs HYROX: Key Differences
This is the question every hybrid athlete asks, and it’s worth answering clearly.
| Feature | Deadly Dozen | HYROX |
|---|---|---|
| Running format | 12 x 400m (4.8km total) | 8 x 1km (8km total) |
| Exercise stations | 12 Labours | 8 stations |
| Equipment | KB, DB, weight plate, bodyweight | Ski erg, sled push/pull, rowing, sandbag, wall ball, burpee broad jump |
| Venue | Athletics track (outdoor/indoor) | Indoor arena |
| Typical competitive time | Under 90 minutes | 60, 90 minutes (men’s open) |
| Specialist equipment needed | No | Yes (ski erg, sled) |
| Scaling option | Yes (formal “(s)” system) | Limited |
| Entry price | Approximately £80 | Approximately £100 and above |
| World Championship | Crystal Palace, Sept 2026 | Frankfurt, annual |
The practical difference for most hybrid athletes comes down to two things: equipment access and running structure.
HYROX requires training on a ski erg and a sled. If your gym has neither, you are at a disadvantage on race day. The Deadly Dozen’s equipment list, kettlebell, dumbbell, weight plate, and bodyweight, means you can train for every Labour in a budget gym or at home. This is a genuine advantage for athletes outside major cities or without access to specialist HYROX facilities.
The running structure is also meaningfully different. HYROX asks you to sustain pace over 8 x 1km, which rewards athletes with a strong aerobic base and the ability to hold form over a longer sustained effort. The Deadly Dozen’s 12 x 400m format is shorter per rep but more frequent, rewarding athletes who recover quickly between high-intensity efforts and can maintain Labour quality under accumulating fatigue.
If you are already training for HYROX or have completed HYROX events, your fitness transfers well. Your running base, functional strength, and ability to perform under fatigue are exactly what the Deadly Dozen demands. Many athletes in the hybrid fitness community race both, and the crossover is real.
Use the HYROX Finish Time Predictor to benchmark your current HYROX fitness before deciding which race to target first, or use both as complementary goals across the season.
How Long Does a Deadly Dozen Race Take?
Competitive athletes typically finish in under 90 minutes. The fastest times in the elite field come in significantly under that, but for the broad competitive field, 75 to 95 minutes is a realistic range for athletes who have trained specifically for the event.
For first-timers and beginners, finish times vary considerably based on Labour pace and how much time is spent at each station. There is no time limit, which means the format rewards completing each Labour properly over rushing through and accumulating warnings.
What “Beating the Race” means: In Deadly Dozen culture, “beating the race” refers to finishing in a time that reflects genuine fitness and race execution, rather than just survival. It’s a community standard rather than a formal cut-off, and it sits at the heart of the event’s competitive spirit.
The best way to build a realistic time expectation is to simulate a full race-pace effort in training: run 12 x 400m intervals with a Labour-quality exercise set between each one, and time the whole session. Your first attempt will almost certainly be slower than your race day effort, thanks to race adrenaline, crowd energy, and the absence of rest-period temptation, but it gives you a working baseline.
How to Train for the Deadly Dozen Race
The Deadly Dozen Triad
The Deadly Dozen Method (DDM) is built around three distinct pillars of fitness, collectively called the Deadly Dozen Triad (DDT):
- Strength: The capacity to move the weights in the Labours with control and form, even under fatigue.
- Labour Fitness: The functional conditioning to perform all 12 Labour stations without technical breakdown, especially in the second half of the race.
- Journey Fitness: The aerobic base to run 12 x 400m at a pace that allows you to complete each Labour properly, not just survive the run to get there.
Training that addresses only one or two of these pillars will leave a visible hole in your race performance. Most self-coached athletes over-develop Journey Fitness (they run well) but underestimate Labour Fitness, particularly grip and upper-body endurance across 12 stations.
Build Your Journey Fitness (Running Base)
The 12 x 400m format rewards athletes with a strong aerobic base and the ability to recover quickly between efforts. The goal is not to sprint every Journey: it’s to run each one at a pace that lets you start the next Labour with enough composure to execute it properly.
Key training priorities:
- 400m interval training: 8 to 12 x 400m at race pace with short recoveries (60 to 90 seconds). This directly simulates the race’s running structure.
- Aerobic base work: Apply the 80/20 principle. Eighty percent of your running should be at a comfortable, conversational effort. The aerobic base is what keeps your Journeys sustainable in rounds 8 through 12.
- Run-to-Labour transitions: Train yourself to move from a 400m run directly into a Labour movement. The first few reps of each station under a slightly elevated heart rate are the moments most athletes lose time through poor form.
Use the Kracey Training Zone Calculator to identify your correct training zones for each run session. Running too hard on easy days is one of the most common training errors for hybrid athletes preparing for events like the Deadly Dozen, and it compounds across a 12-week build.
Build Your Labour Fitness
This is where most preparation underestimates the race. Completing 12 Labours across a 90-minute effort, with running between each one, is a specific adaptation that requires specific training.
Priority movements to master:
- Farmer’s Carry: Train with kettlebells or dumbbells at your target race weight. Focus on grip endurance across longer distances rather than speed.
- Devil’s Press: The most technically demanding Labour for most athletes. Practise the transition from burpee to snatch until it is automatic. Technique under fatigue is the goal, not raw speed.
- Goblet Squat: Full depth is non-negotiable. Train it with race weight at moderate volume to build fatigue tolerance.
- Bear Crawl: Often underestimated. Wrist and shoulder endurance matter more than speed here.
- Snatch: Single-arm kettlebell snatch under grip fatigue is hard. Train both arms equally.
Grip endurance deserves its own focus. The three loaded carries (Labours 1, 7, and 11), the Deadlift, and the Snatch all heavily load the hands and forearms. Add farmer’s carries, dead hangs, and high-rep kettlebell work to your weekly training. Grip failure in the back half of the race is avoidable with specific preparation, it just requires deliberately training for it.
Race-Specific Training Tips
Simulate the full format under fatigue: Once every two to three weeks, run a full or half-race simulation. Run 400m, complete one Labour movement at target reps and weight, run another 400m, complete the next Labour. Even six rounds of this reveals exactly where your Labour Fitness and grip endurance are limiting you.
Complete the Seeding Labour before race day: The Seeding Labour placement assessment determines your wave. Practising it beforehand removes one unknown from race day and gives you a clean benchmark for your preparation progress.
Nutrition and hydration on race day: Eat a solid meal two to three hours before your wave start. The race is long enough that fuelling matters, but short enough that you do not need mid-race nutrition in most cases. Hydrate fully in the hours before and use the time between waves to settle your pre-race nerves rather than second-guess your pacing plan.
Train the movements, not just the energy system: Cardio-only preparation will leave you underprepared at the Labour stations. The Deadly Dozen rewards athletes who can still move a loaded weight cleanly deep into the race, not just those who can run fast on fresh legs.

Frequently Asked Questions
What is the Deadly Dozen race? The Deadly Dozen is a hybrid fitness race held on an athletics track, combining 12 x 400m runs (Journeys) with 12 functional exercise stations (Labours) using a kettlebell, dumbbell, weight plate, and bodyweight movements. Athletes complete the Journeys and Labours alternately in sequence, with no formal rest periods.
How long does a Deadly Dozen race take? Competitive athletes typically finish in under 90 minutes. For the broader field, finish times vary based on Labour pace and conditioning, but the race has no time limit. Beginners should expect 90 to 120 minutes for a first attempt, depending on scaling and station time.
Can beginners do the Deadly Dozen? Yes. The Deadly Dozen has a formal scaling system: athletes who cannot complete a Labour to standard after three warnings have that element adjusted and continue the race, with their result marked “(s)” for scaled rather than a DNF. This makes the Deadly Dozen race genuinely accessible to athletes at different fitness levels.
How is the Deadly Dozen different from HYROX? The main differences are the running structure (12 x 400m vs 8 x 1km), the equipment (no ski erg or sled in Deadly Dozen), the venue (athletics track vs indoor arena), and the number of stations (12 vs 8). The Deadly Dozen is more accessible for athletes without specialist equipment and rewards faster recovery between short, high-intensity efforts rather than sustained aerobic pace over longer runs.
