The family of a holidaymaker who died in Greece are walking the length of Hadrian's Wall in a bid to raise funds to prosecute three doctors.
Christopher Rochester, 24, died after falling from a hotel balcony in 2000.
His family are pursuing a private prosecution against the doctors, who were convicted of manslaughter by neglect, but cleared on appeal.
Stepfather George Cummings will start the 73-mile march in full Roman armour on Wednesday with his daughter Liz.
Mr Rochester, of Chester-le-Street, died of internal bleeding at Rhodes' Andreas Papandreou Hospital after falling from the balcony in Faliraki.
He had been left on a hospital trolley for three hours following the fall, and his kidney was also missing when his body was returned to Britain.
Doctors Stergios Pavlidis, Georgos Karavolias and Mihalis Sokorelos were sentenced to three years in jail but were cleared in 2005.

Mr Cummings said the family were now waiting for Athens' Supreme Court to decide whether the prosecution, which will cost £15,000, can proceed.
He said: "Christopher's family have fought for seven years and we won't rest until we get justice for his death.
"We're about £8,000 short of our target, and just awaiting a trial date when we can return to Greece."
Mr Cummings and Liz, 14, will set off from the Solway Firth in Cumbria on Wednesday, and hope to reach Wallsend in Newcastle within eight days.
They will stop en route at Housesteads Fort in Northumberland for two days of fund-raising on 4 and 5 August.
