No other event can link to the heritage and honour of the Royal Marines Commandos.
This is the only Obstacle Course Endurance Run built by the best for the rest.
From Commando wannabes to eight-year-olds racing with their folks, you can make it as difficult as you can handle.
Many of the 18 obstacles used are exact replicas from the Royal Marines Commando Training Centre at Lympstone in Devon.
One of the obstacles is called the Catacombs of Doom. 'Nuff said.
And while the Commando Series will test your limits, there are a number of difficulty levels here for everyone, from nervous mums and dads searching for something new to teens looking for bragging rights in the schoolyard on a Monday morning.
So are you in touch with your inner Commando?
Can you handle the same tests that the Commandos face when looking to make the grade?
Does the idea of caves, muddy slides and suspended river crossings have you welling-up with excitement?
WELL THEN, WHAT ARE YOU WAITING FOR?
With its historic story, unspoilt ancient woodland and newly discovered set of caves, Hever Castle in Kent is the natural first choice of a venue for the series.
