Brave Darren Weston is fundraising for the Yorkshire Air Ambulance, saying: "If it wasn't for them, I wouldn't be alive today."
The 14-year-old's life was saved after he was rescued from under a bus in Manchester Road, Bradford, in September, and flown to Leeds General Infirmary in just three minutes by the 999 helicopter.
He was in intensive care for a month and has undergone a series of operations for multiple injuries.
His family are convinced the air ambulance flight made the difference.
The full version of this story is in this evening's Telegraph & Argus, and will appear on the website later tonight.
