It's always a challenge to prepare to run a marathon.
This guy REALLY wanted to challenge himself.
Here's why!
Lukas Bates decided to run 26.2 miles in a Big Ben suit!
He ran the marathon in full costume.
His goal was to break the Guinness World Record for fastest marathon as a landmark.
Bates wanted to finish in less than three hours, 34 minutes and 34 seconds.
But, there was a little bit of an issue.
He got stuck at the finish line when the top of the tower got caught and he needed other racers to help him.
Even though he didn't break a world record, he still finished the race in three hours and 54 minutes!
