David Turner has raised over £1,000 for the Arthur McCluskey Foundation, and the Mother's Village Orphanage in Bosnia.
He said: "Given how hard it has been to raise money we have received quite a bit, £1,403 online and we also have offline donations.
"The marathon started as a dream but ended as a nightmare.
"It was very tough and I'm in a lot of pain now but I completed it, I made it to Buckingham Palace and I'm proud of that.
"The marathon organisers had people there to support the runners and someone accompanied me to help me complete it.
"I'm not sure how long it took, the clock had stopped and most people had left when I finished, at half way I was on four hours. But the main thing for me was to complete, which I did and I have that medal.
"Unless you have ran a marathon you don't know how physically hard it is. I'm glad I did it, but it is definitely my last one."
Robyn Shuck, of Grovehill, completed the 26.2 mile challenge and raised £6,543 for Crohn's and Colitis UK.

She said: "London marathon was an incredible experience and running for Crohn's was amazing!
"It was my first ever marathon and I ran it in 4 hours and 55 minutes!"

"I also raised £500 for the charity."
Tom Langdown, from the Gade Valley Harriers in Hemel Hempstead, completed the 26.2 mile challenge in just over 5 hours.
He completed the marathon dressed as a giant elephant weighing 10kg, to raise awareness of The David Sheldrick Wildlife Trust.
Tom said: "It didn't go great, I started off too quickly and I should have known better, as this isn't my first marathon.
"I did a lot of training but I don't think I trained enough in the actual costumer, it was really difficult to move in.
"I completed it in 5 hours and 12 minutes, but my aim was less than 5 hours. On the half way mark I was on 2 hours and 15 minutes, but in the second half I slowed down and had to walk parts, just so I could finish it.
"It didn't go to plan, which is frustrating, but I did raise awareness of the charity and my target was £500, and I am currently at £800."
