Sometimes marathon running stops being about speed…

…and starts becoming something completely different.

Because somehow, over a MILLION people apply to run the London Marathon…

and some of the people who get in decide to run it:

in jeans
in full business suits
in wooden clogs
in four-inch heels
or dressed as Thomas the Tank Engine.

In this episode, we dive into some of the strangest — and strangely impressive — marathon world records ever set.

From sub-2:40 marathons in dress shoes…
to zombie world records…
to groups of runners literally tethered together for 26.2 miles…

these stories somehow get more absurd the deeper you go.

And the craziest part?

A lot of these runners are still faster than most marathoners in normal gear.
