Children taking part in the Mini and Junior Runs are encouraged to raise a small amount of money to help a local cause.
They can, of course, choose any charity of their choice - or opt to support the event's official partner charity.
The 2019 official partner charity is Lincs and Notts Air Ambulance and is funded purely by the kind donations of the people of Lincolnshire and Nottinghamshire.
"The pilots in our bright yellow helicopter fly our skilled doctors and paramedics right to the people who are suffering from the most serious of illnesses and injuries, giving those patients the best possible treatment as quickly as possible. At a time when every second counts, the arrival of our crew can really make a difference and help people when they need us most."
