A race in which competitors aim to ‘beat the darkness’ is being held near Harborough next Saturday (September 12).
The Twilight Run is organised by the same team which hosted the Yeti Run two years ago at Wrongs Farm in Sibbertoft.
The run, at the same venue, will see competitors set off in the early evening, aiming to finish a five or ten kilometre route before nightfall.
More than 500 people are expected to take part this year.
The organisers of the event say: “Challenge yourself over 5km or 10km as you pit yourself against extreme terrain on this hardcore mud run as you attempt to finish before nightfall.
“You will be tested to the max as you tackle manmade and natural obstacles which have been designed to deliver the ultimate running experience.
“One thing is for sure this race is not for your Sunday best as you will get wet and dirty.
“Although not compulsory, if your usual dirty weekend involves dressing up, fancy dress is actively encouraged.”
Competitors wearing head torches are expected to tackle a number of obstacles on the course.
The obstacles include a hay bale tower, monkey bars, balance beams, cargo nets, hurdles and one which is simply called ‘The Pong Pit’.
Anyone who wants to take part can still enter.
Individual entry costs £50 while teams of four or more people can enter at a cost of £45 per person.
There is also a ‘competitive wave’ for runners who want to take part with a timing chip. Entry for the competitive wave costs £55.
Any teams wishing to enter the competitive wave are asked to email firstname.lastname@example.org.
Competitors have to be aged at least 16.
Spectators and supporters are also welcome to attend the event for free, but will not be able to access certain parts of the course.
As well as the Yeti Run and the Twilight Run, the organisers of the events also host another event called Farmageddon near Melton.
