Katie Price was forced to pull out of the London Marathon on Sunday (22.04.18).

The 39-year-old former glamour model promised herself and her fans that she'd complete the 26-mile event even if she had to ''crawl'' to the end in aid of the British Lung Foundation after her mother Amy was diagnosed with terminal idiopathic pulmonary fibrosis - a condition in which the lungs become scarred - last year.

However, the brunette beauty - who was wearing a pair of pink papier-mâché lungs on her back - is believed to have stopped running at around seven miles in.

Katie was expected to complete the course in just under eight hours - meaning she would have crossed the line at around 7pm this evening - but the mother-of-five sparked fears for her welfare when she failed to pass the nine-mile marker.

It's not known why Katie - who recently admitted she hadn't done any training for the gruelling marathon - pulled out of the race but she has been battling a knee injury.

She said recently: ''I haven't gone the distance I did before, because my knees are damaged. There's absolutely no way I could ever not run this marathon. Whatever happens, whatever pain I'm in - it's to make my mum proud in the end.''

And the 'Loose Women' panellist is no doubt devastated that she didn't manage to finish the race as her mother Amy previously expressed how ''proud'' she was of her.

She said: ''I am so proud of Katie. The last few months have been a rollercoaster ride for my family. The main thing is that we raise awareness of what is a much-neglected health area, so the people with the power to do something take notice and act.

''I have a terminal lung condition that took far too long to be diagnosed. A national plan for lung disease will help patients get the right diagnosis and early access to the right treatment and care. Everyone who runs the London Marathon does it for their own personal reasons and the journey they've been on.''
