The London Marathon was held on Sunday and it seems one of England’s best-known landmarks had a little trouble crossing the finish line.

Lukas Bates, from Maidstone, Kent, was looking to get his name etched into the Guinness Book of World Records by completing the marathon while dressed as a landmark.

The current record stands at three hours, 34 minutes and 34 seconds. Bates would officially cross the finish line with a time of three hours, 54 minutes.

While he missed the mark by about 20 minutes, thankfully he did not miss it by just a few seconds while he tried to figure out how to cross the line when the top of his costume clipped the top of the arch at the finish line. The 30-year old would get some help from a race volunteer and another runner in getting under the arch and crossing the line.

For those who are not aware, Big Ben is the more common name for the Palace of Westminster’s Elizabeth Tower that has a clock overlooking the city. It is currently undergoing conservation works.

As for Bates, he says that he has a personal best of two hours, 59 minutes in the marathon, but that was done when he wasn’t dressed up as a huge clock.

Bates has competed in the last four London Marathons and said, “this year I decided I wanted to do something different, have a bit of fun and wear a crazy costume.” And he did just that while raising funds for the Alzheimer’s Society and Alzheimer’s Research UK.

As it stands, the current Guinness Book of World Records record for the fastest marathon time while dressed as a landmark is held by Richard Mietz who set the mark at the Berlin Marathon last September when he ran dressed as the Holstentor city gate in Lubeck.
