The St.Barnabas Lincolnshire Hospice has once again teamed up with events supplier Running Imp to host the 5K fun run at the Showground.
No more entries can be accepted but spectators and sponsors are still welcome.
The Colour Dash is run over a course lined with paint stations which means participants are splattered with environmentally-friendly powder paint every kilometre.
Last year 2,500 fun runners took part and raised an incredible £119,000.
