Definitely no Guinness World Records for marathon man Mark Vaz

It comes after he abandoned his claim on his world record run from Land's End to John O' Groats when questions were raised by runners across the UK.

The Penkridge window cleaner claimed to have run the 860-mile or so route in seven days, 18 hours and 45 minutes, shaving over 31 hours off the previous world record.

But top runners from across the country said it was 'not possible'.

It was understood Mr Vaz had entered the record books in February after completing 240 marathons in 218 days.

But Amber-Georgina Gill, a spokesperson for Guinness, confirmed that Mr Vaz did not hold any Guinness World Records titles at the moment, but had made an application for most marathons run on consecutive days.

Earlier this week Mr Vaz said he had received death threats and had been the victim of trolling on social media

In a statement posted on his Facebook page the fundraiser said: "In regards to running and this record I've never once stated I beat it or wanted to beat it, I did it for charity which is close to me to raise money.

"I will not be going to Guinness now and making it official as I have been hounded by a number of people and it all makes it now all very bitter. Either way I can't win..

"I just wanted to get my point across about why I did Lands End."

In his statement he added that he would now be giving up running 'due to it affecting' his health.

Prior to his run, Mr Vaz had a poster made up and even put it on his support van which read: "World Record Attempt, Lands End to John O' Groats".

Then during the run he tweeted saying he was 'on target for the world record'.

After the run, he changed his Facebook profile picture to an image of himself standing underneath the John O' Groats sign pointing at Lands End, with white writing which read: "LEJOG 7 days 18 hours 45 minutes" – the time he originally claimed to have completed the run in.

Andy Nuttall of ULTRA Magazine, who had donated to Mr Vaz just a couple of weeks ago before his LEJOG challenge, said Mark's originally claimed time would have propelled him to the status as the 'greatest ultra runner who ever lived'.

He added that the ultra running community was not 'witch-hunting' but was just preserving its sport.
