By now most of the surf world has been drenched in footage from Nazare, after Hurricane Epsilon produced some of the biggest waves anyone has ridden.

And the saturation has been for good reason: There's few things in the sport so immediately compelling as watching athletes take serious risks in waves of consequence, in pursuit of an adrenaline-spiked reward they'll remember for the rest of their lives.

But this new Sessions clip from Red Bull -- while also highlighting the surfing -- provides an interesting behind-the-scenes look at the preparation that goes down in the early hours of the morning before the athletes head out on their skis to tackle Nazare.

After all, this isn't the sort of wave you just turn up at and paddle out ... equipment needs to be triple checked and then checked again, all while fighting through the inevitable nerves.

So check out exactly how surfers such as Kai Lenny, Lucas "Chumbo" Chianca, Justine Dupont, Pedro "Scooby" Vianna and Andrew Cotton approach this impressive feat.
