Safety and respect come first – for yourself, your fellow Mudders, and our crew out on course. Tough Mudder is all about teamwork, even at World’s Toughest Mudder, but there are still a few rules to play by.

Keep these in mind as you crush the mud:

• You MUST be able to swim 100 metres to take part in World’s Toughest Mudder as per the guidelines set out in the World’s Toughest Mudder Competition Rules.

• Please refer to our virus safety guidelines for information on if attendance if you feel unwell or are a close contact.

• There is one hydration station available on course, if you have any allergies please check any product details before consuming. Allergen signs will be displayed where appropriate.

• Help your fellow competitors – smartly. Teamwork is still encouraged, but putting someone on your shoulders to get through hanging obstacles like Hangin’ Tough or Just the Tip? Big nope. That’s a safety hazard.

• Be cool out there. No pushing, shoving, or rough behaviour. Be kind to those you may be over-taking on course and warn them you’re coming through without screaming at them. Don’t be gross. Waste goes in bins – not the trail.

• Respect volunteers and staff. They’re the real MVPs. Speak to them if you or others need help.

• Follow the Signs, Not the Crowd. Look out for directional arrows, obstacle warnings, and safety notices along the route. If a sign says “Caution,” we mean it.

• Some obstacles ARE mandatory. Make sure you’re physically ready for the challenge. If you are unable to complete a mandatory obstacle you will be disqualified. 

• Medical warnings and Course Safety signage matter. If you have a heart condition, pacemaker, metal implants, or a history of seizures, do NOT attempt electrical obstacles and take the penalty instead.

• There is one electrified obstacle on course, please do not attempt it if you have a heart condition, metal in your body, history of neurological conditions, or are pregnant.

• All of the obstacles you will face on course will have an obstacle sign in front of them containing safety information. Please make sure you take your time to observe this signage and adhere to any safety guidance given.
