Anthony 'Ant' Gillings, 97, who has lived in Sussex for the past 70 years, will take on a five-mile walk in aid of a charity that supported his beloved wife Peggy.
Ant, who lived in Shoreham for many years and who now lives in Worthing - and still works - recently lost his partner Peggy to dementia.
"This devastating illness, and long journey over many years, was made significantly worse by going blind - a double blow for Peggy, being in the dark and at the same time not knowing where you are or being able to recognise people because you are both blind and losing your memory."
Their 4Sight Vision Support helped the couple "through these dreadful five years" by providing them with support through visits, assessments and equipment.
"This helped Peggy stay in her beloved home for as long as she could and, without their incredible support, this awful situation would have been a lot worse.
"The work that 4Sight undertakes was vital to Peggy and myself to help keep her in her home, as well as providing community events to meet people in similar situations, which helped with this lonely situation.
"I am lucky that at 97 I can still walk and I would therefore like to thank 4Sight through raising much needed funds to help others."
On June 2 at 11am, Ant will set off from Riverside Road at Shoreham Beach and walk to the Ardington Hotel in Worthing - nearly five miles.
"At my age this will take me a few hours."
Ant is hoping people will support his walk and "the fantastic work 4Sight undertakes" by sponsoring him at:
