The adventure run, which consists of a 20-mile long course and contains 200 individual obstacles, is organised by Rat Race Adventure Sports. Last year’s inaugural event in May saw 5,500 runners take part at the same location, with the event culminating in live music performances.
This year, BBC Radio 1 DJ Greg James will perform a DJ set on the Friday night, and indie pop band Reverend and The Makers will also take to the stage.
Participants can take part in one of two courses including ‘The Full Mucker', consisting of a minimum of 200 obstacles over 20 individually-themed zones, and 'The Half Mucker' featuring around 150 obstacles in more than 15 zones.
Gorilla has been tasked for a second year to build a series of permanent and semi-permanent structures for the course, made from a range of materials including steel and wood. A crew of 14 individuals are working on the build ranging from riggers to builders, scaffolders to plant drivers and water safety experts.
The event is capitalising on the large-scale structures from last year, however, a few new structures are being built using materials, such as poles and scaffolding, from eight articulated lorries. Diggers have excavated over 50 pits and trenches through which competitors will have to pass through. The project has a 25-day build period and a six-day de-rig.
The largest single obstacle on the course is the Final Furlong, which is the last obstacle on the course. It sits right in front of Burghley House and measures 7.5m in height.
Andy Gregorek, managing director at Gorilla, said: "We built the world’s biggest assault course for the Rat Race Dirty Weekend in 2013 and, not ones to sit on our laurels, for 2014 we have made some changes. There are some old favourites from last year, some brand new obstacle zones and of course, one or two record breakers."
