We have selected a series of images from the Hartlepool Mail archives and each of them shows people supporting charity runs over the years.
Were you pictured being covered in paint while you ran, or doing 5k round a sports field?
Did you tackle a run at Summerhill or next to the Marina? Take a look and relive the memories.
