This is the heartbreaking moment a London Marathon runner broke down in tears because staff had already started clearing the course and ripping up the timing mats when she was just halfway.
Kerrie Aldridge, from Cardiff, who was raising money for the Miscarriage Association, recorded an emotional video live on Tower Bridge where she sobbed that 'they're already packing up' but vowed to continue to the finish.
Her tearful outpouring comes as other slower runners share their own horrendous experiences of last Sunday's race - including Big Brother's Jack Glenny, who told MailOnline that stewards yelled at him to 'run fatboy run'.
And social media has now erupted with former competitors claiming that back-of-the-pack participants have been subjected to 'disgusting' treatment for years.
Choking on her words, Kerrie said: 'Hi everybody, so I’m still running, look what’s left, I’m halfway.
'The sweeper vehicle’s passed me, they’re packing up, but I don’t care. I’m going to keep going, thank you everyone who’s supported me.'
Later, she wrote on her Facebook page: 'Next came Tower Bridge now I had always been told this would be the moment...crowds everywhere and a wall of sound there would hit you.
'In a marathon support page I had joined so many had talked about the emotion of this one moment.

'Well Tower Bridge was there I welled up I knew this was roughly half way but there were no crowds there were just clean up trucks and lorries both sides of the roads and people going over the bridge going about there daily lives.
'It was heartbreaking I had worked so hard. My tracker was no longer working as they had taken the timing mats up.'
London Marathon has come under renewed fire from runners who claim that slower competitors have been subjected to 'disgusting' treatment for years.
Experiences of stewards hurling abuse at back-of-the-pack participants - such as yelling 'run fatboy run' - has provoked other dismayed runners from previous races to vent their own fury at organisation staff.
Former Big Brother contestant Jack Glenny told MailOnline he would never take part in the event again after 'the proudest moment of his life was ruined' by cruel stewards who poked fun at his weight at made him feel like a 'nusiance'.
She also hit out at the contractors for beginning the clean-up operation on sections of the course, including vital water stations, which were still being used by the slower runners
One user, who shared a picture of two back-of-the-pack runners on an already cleared course, even implied that the problem stretched back as far as 2011
And one 2016 runner, replying to the 'horrific' experiences of a pace setter from last Sunday's race, said she found her own treatment 'disgusting' three years ago.
Pippa Baird wrote: 'Me and my mum did the Virgin London Marathon in 2016.
'We were slow turtles and we had the exact treatment, it was awful and disgusting.
'I hated it by the end and it was just not enjoyable, if it wasn't for my mum in support I would not have finished! I ate more dust on the run than drank water!
'The hype is not worth it at all! If you're not a celeb or a fast runner you're not worth it to them, pointless letting slow people in they don't treat them right at all!'
Her experiences were echoed by a 2015 runner, known as 'cen', who tweeted: 'The course was closed, we were hit by flying objects from the cleaning crew, marshals had given up.
'We were proud of our achievement but definitely did not get the experience.'
Chris Bayley wrote: 'My wife did the Marathon in 2014 and had similar issues with being forced on to the pavements.'
