Incredible moment man carries his former rugby teammate over the finish line at Leeds marathon

The defence coach for the England national team was spotted carrying former teammate Rob Burrow after pushing him for the 26.2-mile (42.1 km) marathon in a specially adapted wheelchair.

However, once the two were within steps of the finish line, Sinfield lifted Burrow and carried him over to complete the race as the crowd cheered on.

Many reacted to the heartfelt moment, as one fan wrote: "This is beautiful, so much love, brothers in arms."

Another said: "Such an inspirational man! Two of my favourite players growing up. Surely he gets a knighthood at some point?!"

While a third marvelled: "Everyone needs a friend like Kevin Sinfield. What an absolute hero! Doing Leeds proud."

Two years later, he received an MBE for raising money and awareness of the condition.

Sinfield revealed that the team's fundraising efforts for the inaugural Rob Burrow Leeds Marathon had raised over £3 million (AUD $5.6 million) for numerous charities.

Sinfield began raising money shortly after his friend was diagnosed.

“It’s the time together I’m looking forward to,” he told the outlet.

“We had some really funny moments during the Leeds 10k when we did a trial run in anticipation for this and while it’s difficult for him to communicate, I know when he’s laughing, and you can see it. We’ll have some fun, I promise you that."

Sinfield admitted his notable cause initially began as a 'mate running for another mate'; however, it has now evolved into something bigger.

“The money is great but most importantly, it provides hope,” Sinfield said.

“People have been left alone with MND in the past, ashamed to come out of their homes. Now, they can live their lives and have hope that there could be drugs that can slow this down, and one day there will be a cure.

“The money raised gives guys far smarter than me a chance to do their job. We now have a fighting chance at a cure because of the efforts of everyone.”
