Ready to test your grit? Our reporter dives headfirst into the mud, sweat, and glory of the Commando Series, the obstacle course race inspired by the legendary Royal Marines. Here’s the full debrief.

In recent years, the world of fitness has seen a seismic shift. People are trading pristine treadmills and predictable road races for the raw, exhilarating challenge of obstacle course racing (OCR). Events like Tough Mudder and Spartan Race have exploded in popularity, but a unique UK-based event, the Commando Series, caught my eye. Promising an authentic taste of Royal Marines training, I was thrilled to accept the challenge and report back from the front lines.

The Commando Series isn’t just another mud run. It’s an OCR meticulously designed to replicate the grueling obstacles and demanding conditions of modern commando training. It’s an invitation to experience the mud, sweat, and sheer determination that forges one of the world’s most elite fighting forces. While that might sound intimidating, the event is cleverly designed for inclusivity. It’s not a timed race; the focus is on teamwork, personal achievement, and having an unforgettable experience. With three distinct intensity levels, it welcomes everyone to the starting line.

Commando Series: Your Ultimate Guide to Conquering the Course

Whether you’re a seasoned OCR veteran or a curious first-timer, this guide will provide you with a comprehensive overview of the Commando Series, from the obstacles you’ll face to the training you’ll need and the gear that will get you through to the finish line.

Choosing Your Challenge: The Three Intensity Levels

The Commando Series brilliantly caters to all fitness levels and mindsets with its tiered system. Understanding these options is the first step in your mission.

• “Just Get Me Round”: This is the perfect entry point for beginners or those who want to enjoy the experience without extreme pressure. You’ll face the core obstacles and get the full muddy experience, but with a focus on completion and fun over intensity.
• “Treat Me Like a Commando”: This is the authentic experience. For those who want to truly test their limits, this level adds extra challenges. Participants carry a pack and a replica rifle, adding weight and difficulty to every obstacle and every step. It’s a true test of physical and mental endurance.
• “We Are Family”: A fantastic option for families and younger participants. This wave is designed for teamwork, allowing parents and children (ages 8+) to tackle the course together, creating lasting memories while navigating a fun, slightly modified set of obstacles.

The Race Day Experience: From Clean Recruit to Mud-Covered Commando

The atmosphere on race day is electric. From the moment you arrive, you’re immersed in a world of military-inspired camaraderie and nervous excitement.

Arrival and Registration

After arriving at the stunning, historic grounds of venues like Hever Castle, you’ll head to registration to pick up your race kit. This typically includes your official Commando Series t-shirt and, crucially, some camouflage face paint to help you look the part. The event village is a hub of activity, with music, food stalls, and a palpable buzz as participants prepare for the challenge ahead.

The Commando Warm-Up

Forget a light jog and a few stretches. The warm-up is an event in itself, led by enthusiastic instructors (often with real military backgrounds). It’s a dynamic, high-energy session designed to prepare every muscle for the ordeal to come. Many participants find themselves breathless and sweating before the race has even begun! The key takeaway here is constant motion—once the warm-up starts, you don’t stop moving. It’s the first taste of the commando mindset.

The Briefing and The Start

Once you’re thoroughly warmed up, you’re led to a briefing area. Here, you’re not just told about the course; you’re indoctrinated into the Commando ethos: Courage, Determination, Unselfishness, and Cheerfulness in the face of adversity. The importance of teamwork is heavily emphasized—you will need to help your fellow commandos, and they will need to help you. With a final motivational roar, you’re sent off to the start line, and the adventure begins.

Preparing for Battle: Training and Fitness

While you don’t need to be an elite athlete, a solid base of fitness will make the experience far more enjoyable. The course is approximately 7km over incredibly varied terrain—from grassy fields and dense forests to thick mud pits and concrete paths. You can walk parts of the course and skip any obstacle you’re not comfortable with, but preparation is key.

Your Training Plan Should Focus On:

• Functional Strength: You’ll be pulling, pushing, climbing, and crawling. Incorporate bodyweight exercises like pull-ups, push-ups, squats, and lunges into your routine. Grip strength is vital for obstacles like monkey bars, so add dead hangs or farmer’s walks.
• Cardiovascular Endurance: A mix of steady-state running and High-Intensity Interval Training (HIIT) will build the stamina you need. Try to run on trails or varied terrain to simulate race conditions.
• Mental Resilience: OCR is as much a mental game as a physical one. Practice pushing through discomfort during your workouts. The ability to stay positive when you’re cold, wet, and tired is the ultimate commando trait.

Essential Gear: What to Wear and What to Bring

Your choice of gear can make or break your race day experience. Comfort, protection, and practicality are your primary objectives.

What to Wear on the Course:

• Clothing: Do not wear anything you want to keep clean! You will be submerged in mud and water. You’re given a race t-shirt, but it’s wise to wear a long-sleeved base layer underneath and full-length leggings or trousers. This will protect your skin from scrapes and scratches while crawling. Avoid cotton at all costs, as it absorbs water, becomes heavy, and will make you cold. Opt for technical, moisture-wicking fabrics.
• Footwear: Standard road running shoes won’t cut it. You need trail running shoes with excellent grip to handle the mud and slippery surfaces. Look for shoes that also drain water quickly.

What to Bring for After the Race:

The finish line isn’t the end of your day. Being prepared for afterwards is crucial for your comfort.

• A Complete Change of Clothes: This is non-negotiable. You’ll want dry, warm clothes, including socks and underwear.
• A Towel: A large, warm towel will feel like the height of luxury.
• Clean Shoes: Don’t forget a pair of flip-flops or trainers to change into.
• Wet Wipes and a Plastic Bag: There may not be hot showers. Wet wipes are a lifesaver for cleaning off the worst of the mud. A large plastic bag or bin liner is essential for quarantining your filthy race gear for the journey home.

The Commando Series is more than just an obstacle course race; it’s an adventure that tests your body, your mind, and your spirit of teamwork. It’s a chance to get gloriously muddy, overcome challenges you never thought possible, and share an incredible sense of accomplishment with hundreds of other participants.
