Southend marathon runner Nick Palmer to be remembered with family day
The family of a runner who died after completing a half marathon said public support had "carried us through" after donations approached £10,000.
Nick Palmer, 37, collapsed at the finishing line of the event in Southend, Essex on 8 June.
A fundraising page in his memory has received more than £10,000, which will be donated to charity.
Nick's brother Darren said a family fun day, combining Nick's favourite sports, was also being set up to raise funds.
"Nick was part of a running team, a football team and his local pool league," Mr Palmer told BBC News.
"We're trying to organise a family day in September that brings all of those together."
Mr Palmer said his brother's death had hit him, and his parents Alan and Linda, extremely hard.
"Because his death was so sudden, it was very shocking for all of us," he said.
"But the support and the messages we had from people carried us through those first few weeks."
Mr Palmer said money raised at the family day, and from the donation page, would be given to Great Ormond Street hospital (GOSH) in London, where his brother's son George received treatment.
He said he had been in contact with the hospital about setting up a "Brighter Future Fund", which friends and family could put money in to.
"Lots of people wanted to do something to show they cared.
"One of Nick's friends has done a [sponsored] walk around Southend to raise money in his memory. Another is planning a 100-mile bike ride," Mr Palmer said.
"It would be good if we could pull everyone's efforts together into one place, and donate the money to GOSH in Nick's memory."
