Watch: This man racing a London underground train between stops is heart-stopping

Prepare to watch the most exhilarating 2 minutes of video in your day.

James Heptonstall and his mates have come up with a "fun" way to spend their days by answering the question we've all thought about while waiting on a train/bus/tram: 'Would I be quicker walking?'. Or running in their case.

In this video, Heptonstall gets off the Tube at London's Mansion House station and attempts to sprint the quarter mile to Cannon Street station in the 1 minute and 20 seconds it takes the train to arrive.

And just in case you think this was a once off, it's something they do a lot. We know that someone already raced a Luas dressed as Sonic, but did they get on and off it between stops? Because that needs to happen. Actually, now that we think about it, the Luas is so slow and stop riddled in places that it really wouldn't be much of challenge.
