On Sunday we ate snacks, slobbed about on the sofa and watched as about a gazillion runners took to the streets of London to run 26 miles aka complete a marathon out of their own free will.
And whilst we spent a lot of time questioning their sanity and wondering whether they were sure they wanted to do so much exercising in one
sitting, er, standing, TOWIE's James Argent's sister Natasha was amongst the runners and completed the race in a time of 3.44.20.
Which would be RIDICULOUSLY IMPRESSIVE, if Twitter users and eagle eyed fans weren't so sure she cheated - after noticing that none of her 'split times' were recorded at numerous check points along the route.
They also noticed that Natasha started the race at 10:16 and reached the 20k mark by 12:33 - meaning it took her 2 hours and 17 minutes to run - but later reached the 40k mark at 13:21 - little under an hour later.
Her split time sheet shows she finished the race at 14:00:40, and Twitter users have been questioning how this could be possible given her first 20k split time and how her tracker went off radar for such a long time.
They wrote: "Natasha should be made to give her medal back and banned for life", "DISGRACEFUL! How did she sleep last night? Should be ashamed... And under a charity name too!"
The charity she was running for London Youth added: "We are aware of the allegations against a #LondonMarathon runner re chip discrepancies & have notified #VMLM2016 who are looking into it".
Take a look at all the evidence and make of that what you will.
