The determined sister of a missing cruise ship worker is running the London Marathon in honour of their brave mother who is losing her sight.

Almost three years have passed since Rebecca Coriam vanished off the Disney Wonder Cruise liner as it was sailing off the coast of Mexico.

Now as the Coriam family prepares to face their daughter’s employers in US courts, her heartbroken sister is running the London Marathon in honour of their mum – who has never given up her fight for the truth, despite battling to save her sight.

Ann, 54, of Guilden Sutton, suffers from type one diabetes, but has never let this get in the way of her mission to find out the truth of what happened to her ‘sports-mad’ daughter, when she vanished without a trace on March 22, 2011.

Now facing losing her sight – a side effect of her condition – Ann could be placed with a guide dog within the next year, and is currently going through the matching process to find the perfect pooch.

“Bex was always the runner,” said Rachael, who works at Carden Park Luxury Golf Resort and Spa, and said her sister would be proud was running for Guide Dogs for the Blind.

“She always wanted to run the London Marathon, that is why I decided to do it last year. I love running now.

“Last year I ran it with colleagues at the Doubletree by Hilton, we raised hundreds of pounds for The Hilton in the Community Foundation. This year I want to do something closer to home.”

Rachael, 28, said she decided to raise money for Guide Dogs for the Blind in the hope she would be able to raise much needed cash for a charity which will support her mum in the future.

“It is a fantastic charity and it is amazing how much they do to help blind and partially sighted people enjoy the same freedom of movement as everyone else,” said Rachael, whose mum became one of the first insulin pump wearers to scale Mount Kilimanjaro when she placed a memorial to Bex at the summit last year.

“My mum is losing her sight due to a side effect of diabetes, she is currently going through the process of guide dog matching. It is likely she may have one within the next year,” she said.

The race comes as her parents Ann, 54, and Mike, 60, prepare to face Disney in US courts in a bid to find out the truth about their daughter’s disappearance.
