Fundraising walk for Portsmouth neonatal unit
2 March 2013 Last updated at 16:21 GMT
More than 100 people are walking 20 miles around Portsmouth to raise funds for the neonatal unit at the Queen Alexandra Hospital.
The walk has been organised by Lorraine Blackburn, whose baby son was the first to be treated at the hospital's neonatal intensive care unit when it opened four years ago.
Owen, born 13 weeks prematurely, later died.
Since then Mrs Blackburn has raised more than £60,000 for the unit and is a full time ambassador for the charity Ickle Pickles.
