Reign of Terror

Reign of Terror is a mud run with challenges like no other. Set in the spectacular surroundings of the medieval village of kells, County Kilkenny you can be sure that’s it’s not  just the challenges that will take your breath away. This historical village will immerse you back in time (and mud!) The natural uneven, hilly, marshy terrain in Kells provides the perfect landscape for such an event. This scenic backdrop and perfect race day terrain combined with our design team’s epic challenges delivers a mud run experience in a class of it’s own. Read on for more information on this one of a kind event.

Leaving Kells

Stewards will guide cars from car parks onto the road.

Given that people will be tired, wet & dirty please take extra care.

What to Wear

  • Base layer tops and leggings that are aerodynamic. Ensure that tops have long sleeves to protect your arms and elbows during the run.
  • A couple of thin layers will provide more heat than one heavy layer.
  • Thin breathable layers will not weigh you down in mud and water.
  • Waterproof socks or double skin socks.
  • Tight fitting trainers. Trainers that are tightly laced and fit closely are far less likely to slip off in mud and in water.
  • Gloves will keep hands warm and allow grip at challenges. Fingerless cycling gloves are good.
  • A skull cap that is not a hindrance or danger to other contestants.

What NOT to Wear

  • Anything made of fleece or non breathable fabric. This will weigh you down when you go through water and mud.
  • Baggy Clothing. These will weigh you down when they get coated in water and mud and may also hinder you at challenges.
  • Jewellery – This will either get lost, broken or pose a safety risk of getting caught on something.
  • Spiked or studded shoes are prohibited for safety reasons and anyone who turns up with them will not be permitted to race.
  • Trainers that have tape strapped around them.
