A father fractured his ankle while raising over £3,000 for charity in memory of his baby son.
Billy and his twin Jimmy were born prematurely on September 9, 2013, weighing just 2lb and 1.5lb respectively.
Mr Shelley and ten friends got together on January 18 to walk from Brighton to Wallington for the hospital.
He said: "We all keep looking at Billy and Jimmy photos on back of our jumpers which kept us going.
"We have raised between £3,000 to £4,000 we are still wait for money to come in.
"Myself and nine others walked from Brighton Pier and a few of us made it back as far as the Caterham roundabout - we blistered our feet and everything.
"I even fractured my ankle but when you consider I lost my son after 19 days you just get on with it."
Mr Shelley said a massive thank you to all his friends who tackled the long walk with him.
