Good question! Knowing the M25 is 117 miles gives you a superpower: you can now calculate how much of your life you’ve wasted on it. For example, if you commute 20 miles each way, you’re driving about 17% of the whole ring every day. That means in a year, you’ve literally driven the M25 more than 30 times. Congratulations, you’re now an honorary member of the Circle of Slightly Flustered Drivers.

Also, 117 miles is exactly the length of 2,048 football pitches laid end to end. Or, if you prefer, the height of 2,208 Eiffel Towers stacked on top of each other. I like to picture a giant robot made of M25 tarmac, but that’s just me.
The Real Length? Emotional Miles.
Let’s be honest: the emotional length of the M25 is what really counts. A 10-mile stretch between junctions 10 and 11 during rush hour feels like a 100-mile crawl through molasses. And let’s not even talk about the M25 car park—I mean, the road—near the Sevenoaks interchange. There, time bends. Minutes stretch into hours. You start naming the cars around you. “Hey, Susan the Skoda, nice wing mirror.”
But the official 117 miles? That’s just the physical distance. The mental distance is infinite.
