A bakery has been racing to make 8,000 stottie sandwiches ahead of a historical run.
The 5.9 mile (9.5km) Blaydon Race from Newcastle city centre to Blaydon, in Gateshead, is based on the lyrics to the 1862 song by Geordie Ridley, and participants traditionally receive a filled bread bun at the finish line.
Pink Lane Bakery operations manager Abe Chirgwin said staff had been working "genuinely tirelessly" for days to bake the snack, native to north-east England.
The race begins at 19:30 BST, with road closures including on Quayside Road, Scotswood Road and Blaydon Highway.
Five thousand runners are taking part in this year's run, organisers say.
Mr Chirgwin said it had been a "massive operation" making a variety of ham and pease pudding, cheese savoury and vegan stotties for the finishers.
Baker Mick Allinson, who had been working the mixer for three consecutive days, said it was a simple process, but a "long drawn-out job".
The team made 4,000 loaves which were cut in half to make 8,000 sandwiches.
Road closures have been put in place on both sides of the Tyne for the race.
