RUGBY league legend Kevin Sinfield has now raised more than £2m after he ran 101 miles in 24 hours without sleep in aid of former teammate Rob Burrow, who has motor neurone disease (MND).

The 41-year-old from Oldham completed his Extra Mile Challenge, starting from Leicester Tigers' Mattioli Woods Welford Road Stadium, where he coaches, and finishing at Leeds Rhinos' Headingley Stadium, where he served as captain and won an impressive collection of silverware alongside Burrow.

As he arrived at Headingley on Tuesday, November 23, clearly in great discomfort, he was cheered on by around 1,000 fans and his great friend Burrow, who was diagnosed with MND two years ago, was there to welcome him in an emotional atmosphere.

The remarkable feat follows Sinfield running seven marathons in seven days last December which amassed £2.7m.

And now the Extra Mile Challenge has generated more than £2m through a Giveasyoulive crowdfunding page as well as an extra £378,000 through Gift Aid.

The money will be split between the Leeds Hospitals Charity appeal to build the Rob Burrow Centre for MND supporting people living with the disease and their families, and the Motor Neurone Disease Association.

After the gruelling run, Sinfield, who was accompanied on the last leg of his run by Burrow's wife Lindsey and oldest daughter Macy, says he was driven by the presence of his old teammate.

"It was really tough at times, especially the end, but it's down to my little mate here," he told the BBC.

In a message on his recording device, wheelchair-bound Burrow said: "Today is an amazing day for the MND community. It will benefit every sufferer.

"To my amazing friend Kev, you don't realise the impact you have had on me and all the MND community."

The England international was also accompanied during the run by former teammates Jamie Peacock, Jamie Jones-Buchanan, Gareth Ellis and Barrie McDermott, along with politician Alastair Campbell and Leeds triathletes Alistair and Jonny Brownlee.

Burrow's dad Geoff lauded Sinfield after the challenge.

He said: "It's nothing short of a miracle, really. He's super human.

"We've all been part of a big family ever since the famous Leeds team achieved what they achieved, he's like another son to me."

Geoff, whose emotional appeal for central funding is thought to have played a key role in the government's decision to award a £50m grant for MND research, added: "It's going to take the ball over the line, just watch this space.

"I'm hopeful all the time but this is making a difference.

"It's not just the rugby league family any more, it's rugby union, it's the sporting family, the whole country."
