The supernova 5K is set to return to Falkirk this weekend after the success of the event in the town in the past.
Runners have been asked to dig out their fluorescent clothing and grab anything that glows and flashes for the event.
Those participating will run the route around The Kelpies in Helix Park which will be lit up to create a spectacular sight.
People of all ages and abilities have been invited to take part.
They also have the option of using the opportunity to fundraise for one of Supernova's Affiliate Charities, which are local and national.
This includes Strathcarron Hospice in Denny which is marking 40 years of service this year.
While Saturday November 13 and Sunday November 14 have sold out, there are still remaining spaces for 8pm on Friday November 12.
