The mum of five was running the marathon to raise money for the British Lung Foundation on behalf of her mother Amy, who has sadly been diagnosed with a terminal condition.
Katie had to pull out from the marathon after she had problems with her knee and sources have said that the heat got to her too.
Uploading a short video to Instagram Katie said:
‘I did train for the run, tried my best in a heavy outfit and if my mummy is proud that’s what matters to me.’
One of her followers commented on the vidoe and said:
‘She didn’t put much effort in she’s meant to be a celebrity and you would think she would raise more than £2000. My husband walk 96 miles in rain sleet snow and winds in 5 and a half days recently and raised nearly £1500 now that’s what u call effort (sic).’
While others where full of congratualtions as one person said:
‘What a fantastic achievement. 8 miles. Knee injury “what knee injury”
