Tracey Cramond from Darlington said she was "gobsmacked and totally shocked" to become the millionth person to complete the Great North Run.
She was presented with a special award by Lord Coe, a few minutes after crossing the finishing line at South Shields.
Tracey was running this year in support of the Butterwick Hospice in memory of her mother, Lynn Liddell, as she explained in her fundraising page online:
Last year I lost the most precious person a daughter could have, my Mom. I will be running in her memory to raise funds for a truly remarkable charity who do so much for so many. I will be the legs my Mom did not and will never have, because she is the wind beneath my wings.
After the run, Tracey thanked the supporters who cheered everyone along the way:
It was incredibly hot today, I think a lot of runners have struggled, I did struggle today too...the crowd this year were phenomenal, they have really done us proud. You get to a point where you're feeling really low, and then all of a sudden there's this spurt of enthusiasm from the sidelines, so you just keep going, it's amazing.
