About Dirty Weekend
You can take part in this event on your own or as a team. The average time to complete the course is between 4 - 6 hours, but the record currently stands at a blistering 2hrs 34m!
It's a monstrous course - in the grounds of one of England's finest Elizabethan Country Estates - with up to 200 obstacles and you can choose to do 13 or the full 20 miles...or the Dirty Double - 40 miles!
If you fancy a shot at the silverware (there's a cup to be won), then start your training now! Warning, this is not your normal mud run!
