Watch: the Green Hell drenched in treacherous rain

The Nürburgring in the dry presents drivers with one of the toughest racetrack challenges in the world. 13 miles of forest-scything asphalt, 73 corners, a whopping 300m of ascent from the lowest point to the highest: the enormity of it is off the scale.

Throw run off areas that make F1’s Monaco circuit look like a desert wasteland into the mix, and you’ve just about got the scariest, most unforgiving test in motorsport. They don’t call it the ‘Green Hell’ for nothing.

At the annual 24-hour race around the Nordschleife, that task gets even harder as teams battle fatigue and changing conditions to go as far and as fast as the clock will allow. Drivers often do stints of three to four hours at a time, and crashes are common.

Especially when it’s raining. Last weekend the Nürburgring 24 was red flagged for four hours due to an insane level of rain and hail that made the circuit virtually impossible to drive. And judging by the video above, it wasn’t exactly plain sailing when the race finally resumed.

Riding on board with Peter Dumbreck in Falken’s 991 GT3R, the footage gives you an idea of how little visibility there is amongst the spray, and how the braking zones balloon in size with the lack of available grip.

No wonder a third of the field didn’t make it to the end.
