Leeds model Nell McAndrew was among more than 54,000 people competing in the Great North Run.
Nell, dressed as Catwoman, was running the 13 miles from Newcastle and South Shields for the fourth time.
She said: “My son Devon, who’s five, suggested the outfit. We’ve got a bit of a superhero theme running in our house at the moment.”
The run was started by the widow of a Red Arrows pilot killed in a display last month.
Dr Emma Egging watched silently as the Red Arrows flew over the start line in the “missing man” formation, in honour of her late husband Jon.
Flt Lt Egging was killed when his Hawk jet came down near Bournemouth Airport in Dorset. Dr Egging, an academic at the British Museum, was using the run to launch The Jon Egging Trust to support youngsters and help them fulfil their potential.
