Keen runner Matt Campbell, 29, slumped to the ground after 22.5 miles as temperatures hit 24C on Sunday.
The chef received immediate medical treatment at the scene but died later in hospital.
Now members of a marathon training page on Facebook have urged runners to cover the 3.7 miles he was unable to complete and donate a £5 “entry fee” to his chosen charity – using the hashtag #FinishForMatt.
One runner wrote: “We've all given each other support over the last few months, and a small gesture of solidarity would be to 'finish' the run for Matt.
“It may be in London, Somerset, Manchester – wherever you are – but if as many people can do a 3.7-mile run on Saturday, and give a £5 'entry fee' to Matt's JustGiving page, I think that'd be a nice gesture from us as a group.”
Matt, of Kendal, Cumbria, had raised £2,000 for the Lake District-based Brathay Trust ahead of the race.
It helps young people by encouraging work in the community.
But, by today donations have passed the £83,000 mark.
One well-wisher, who donated £3.70 today, wrote: “So sad you are gone. This is for the distance to finish. Love to your family and friends.”
Another added: “An inspiring young man. Along with millions I thoroughly enjoyed watching his genius on Masterchef. His family must be very proud.”
And one more commented: “I too ran the marathon on Sunday and now consider myself to be one of the lucky ones to finish this great event.”
Ahead of the race Matt told of his pride at raising money in honour of his dad Martin, who died two years ago.
He said: "Martin helped change many lives for the good. He was the most inspirational man in my life.
"Although he won't be there in person, I know he will be there in spirit and I'll be running for him."
He tweeted a photo of himself minutes before the start of the race saying: "Lets do this!"
Matt came second on BBC's Young Chef of the Year when he was 20 and last year reached the semi-final of MasterChef: The Professionals.
A MasterChef spokeswoman said: "We are shocked and saddened to hear about Matt. "It was a privilege to have him on the show.
"He will always be remembered for producing some of the most innovative and groundbreaking food that we saw on the series."
