Runners who have lost over 10 stone prepare to take on Asda 10k run in SheffieldÂ

 Brett Sutcliffe, who has lost seven stone in weight, is preparing to run the Asda Foundation Sheffield 10K this Sunday in memory of his mum.

  Mark Coulson is also getting ready to take part in the race, which will be the tenth 10k run that he has done this year to raise awareness of men's mental health.

When PE teacher Brett realised that he weighed 22 stone he decided he had to do something about his weight to set a good example to his pupils.

He started to follow a healthy eating and fitness regime, and is now looking forward to taking on the 10k  to raise money for Sheffield Hospitals Charity.

He said: ' I am running to raise money for the Sheffield Hospitals Charity as they do a fantastic job under very difficult circumstances.

'In the last seven years they have looked after my own children, my terminally ill late mum and an older relative with compassion.'

'I wish to raise funds so they can really give the full service the staff on the ground want to but are often restricted by budget.'

Mark, who decided to run all Asda Foundation 10k runs across the country, will be raising funds for Hull Man Club, a place he co-founded where men can go to talk through issues.

Mark, who has lost five stones and three pounds in weight, decided to set up the organisation after two male friends committed suicide.

He said: 'It will mean a lot to me to complete this challenge, not just for me but for people to realise you can achieve anything if you work hard. No matter what you are going through you can get through it.'
