Around 11,000 people will be taking part in a 26-mile charity walk in memory of Harry Moseley today.
11 year-old Harry died from a brain tumour last October.
He selflessly and tirelessly spent his time raising money for charity by making and selling bracelets and set up the Help Harry Help Others campaign.
Thousands of people including many celebrities have backed his campaign.
It's hoped that today's event will help raise more than £300,000 for Birmingham Children's Hospital and Acorns Children's Hospice.
Harry's mum Georgie will officially start the walk at 9am at Rookery Park in Erdington.
They'll be bracelets available for everyone taking part in the event - for a minimum of donation of £5 you can get one and for £10 you can get three. All the money will go to charity.
Yesterday cyclists took part in another charity event in memory of Harry.
They rode 104 miles from Blackenhale School in Sheldon where Harry was a pupil to Wembley Stadium in London.
