Captain Tom Moore delivered a message of hope after completing his inspiring fundraising challenge for the NHS.
The WW2 veteran completed the hundredth length of his Bedfordshire garden this morning with a special guard of honour by the 1st battalion of the Yorkshire Regiment.
When he crossed the finish line he had raised £12.2million in the process - and the figure continues to rise at a rate of knots, now standing at nearly £12.5million.
The 99-year-old has become a point of national hope and inspiration since he began his challenge last week.
Speaking at the finish line, Captain Moore told BBC Breakfast he felt "fine" and that he was "surrounded by the right sort of people".
Of the coronavirus pandemic, he added: "We will get through it in the end but it might take time, but at the end of the day we shall all be okay again... the sun will shine on you again and the clouds will go away."
Captain Moore was shown a video featuring multiple celebrity well-wishers including cricketer Ben Stokes, TV personality Judge Judy Sheindlin, and singer Michael Ball.
He planned to reach his target before his 100th birthday on April 30 to help those on the front line of the coronavirus crisis.
Captain Moore said plans for his party have been affected by the virus, and he joked everyone would have to keep six metres away from him "because I must be something horrid".
He added that the national outpouring of love and support for him was "a party enough for me".
Captain Moore's daughter Hannah said he had become a "beacon of hope" during challenging times.
Speaking to ITV on Thursday morning, the captain said the public generosity had been "unbelievable".
He added: "Our country and all our nations, we're all so generous in all sorts of ways. But it's for a super purpose.
"Nurses, doctors and all the back-up workers, they deserve everything we can give them."
Cpt Moore, who lives with his family, was given a special mention in a press briefing on Wednesday by Health Secretary Matt Hancock, who described him as an "inspiration".
The Ministry of Defence tweeted its congratulations as he finished his walk.
After being told he had become the largest single fundraiser for the JustGiving donation site, Captain Moore said he would continue with his fundraising.
"We've fought so many battles and we've always won, and we're going to win again," he said.
"Please remember tomorrow is a good day and we will get through it in the end... I shall continue walking."
There have been multiple calls for Captain Moore to receive a knighthood for his charitable actions, and there is an online campaign for children to make him birthday cards.
His daughter said the local postmaster had already been "inundated" with messages ahead of his birthday.
Originally from Keighley in West Yorkshire, Captain Moore trained as a civil engineer before enlisting in the Army for the Second World War, rising to captain and serving in India and Burma.
