Vince Dilig, 25 from Ashstead, donned the 62cm by 62m suit with the aim of finishing the 26.2 mile course in three hours and 15 minutes.
The unconventional competitor sported the Domino’s inspired cardboard costume for much of the race, drawing cheers and confusion from the crowd in equal measure.
He was also seen refuelling on garlic and herb dipped crusts on his way around – using his helmet to top up on dip.
When asked about his bizarre choice of running gear, he said: “Nothing gives me the inspiration to run like a Domino’s pizza.
“So, I thought, why not? It’ll get me round the course in fine fettle.
“With a little determination, and a lot of garlic and herb dip, anything is possible.”
Vince has completed two marathons in the past with his fastest time being three hours and 29 minutes in last year’s London race.
He’s also completed a half Iron Man in five hours and 46 minutes after swimming, cycling and running his way to the finish line after 70.3 miles.
He also has the Hampton Court half under his belt after completing it in February 2025.
However, he’s never run in a fancy dress costume before but with four big races down, he wanted to add an extra challenge to the route.
Vince said: “I wanted to push myself out of my comfort zone.
“It was a challenge to get over the finish line when I first started, but now I’m more seasoned I want to try something new.
“People won’t remember my time, but they will remember me if I’m wearing a pizza box.
“I’ve had so many high fives and I feel like being dressed like this does spur people on.
“That’s the beauty of the London Marathon, people wear some outrageous costumes and still make it to the finish line.
“I think some people were jealous of my garlic and herb dip supply, so many people asked for some on my way round and I was happy to oblige.”
Vince spent seven months training for the 26.2 mile run and hasn’t had any alcohol since New Year’s Eve.
His strict training regime included a long run every weekend which is between 25 and 35 kilometres.
And his strategy for the main event is to make sure to have enough electrolytes to keep him going – and he’s hoping he can get this from the garlic and herb dip.
He even treated himself to a Domino’s last night and said: “I thought I’d get myself in the mood and order one in last night.
“Pizza is a good choice because of the complex carbs anyway, so it seemed very fitting.”
