Assault on Lambton Castle


 *** Event Poster***  

It took us 3 years to find this unbelievable location in the NE and now we return for our second year to a bigger, wetter, muddier course to test you and your mates. This is the best location in England for an OCR event.

Located at the awesome Lambton Castle, Chester le Street, Durham. This is the No Ego Challenge season opener and is not to be missed. Don't be fooled by the picturesque setting, this will be a fast and furious 12km or 5 miles of military inspired hell. This fierce course features 50+ epic obstacles, tons of filthy mud, forests, lakes and the River Wear plus some of the finest and varied terrain your tired legs are likely to ever experience. This is a course designed to test your physical and mental ability to the absolute limit. Have you got what it takes? Survive the course and return to base HQ to enjoy some great banter in the buzz of the event village.

Junior mud challengers can test them selves on the I mile junior challenge.

1 mile Junior event.

Don't think the Assault on Lambton event is only for the adults, We have a fantastic treat for all your budding muddy kids in a 1 mile (ish) trails through mud, bogs, commando nets, tunnels and over walls to finish with a smiling dirty face. This distance is for 6-14 year olds only.
