Warning: This story may offend. The new road surface of Surrey landmark and cyclists' favourite Box Hill has been defiled by a lewd graffiti artist.
The famous climb has been resurfaced ahead of the Olympic Games road race in July, but now the pristine tarmac has been decorated with a white spray-painted item of male anatomy.
The size of the 'artwork' means that it would be clearly visible from aerial television shots if left on the road when the Games take place.
It's been a long-held tradition to decorate the roads along the route of road races, particularly on climbs. And this certainly isn't the first time that someone has created a sizeable likeness of a gentleman's genitalia.
Needless to say, the graffiti has caused widespread reaction from cycling fans on the internet, from outrage to amusement. Here are a selection of comments left on Cycling Weekly's Facebook page.
"Cretins," said Martin Emmerson. "Why bother to wreck peoples rides with that!?" added Dylan Edwards.
Brian Sewell, sorry Peter Sarwan gave his critique: "Not a bad effort, but it needs pubes and better definition around the b*****ks."
Others are more concerned about the welfare of the artist himself. "If that's anatomically correct, based on the culprit who drew that, then that guy needs to see doctor," said Ross J Higgins.
Voice of reason Colin Ewing concluded: "Why is anyone bothered by this? Has the British sense of humour totally gone? Arguably not all that funny but it's not hurting anyone, is it."
And ever the cyclist, Simon Bradeley was more interested in the rider's technique than the image on the road: "Forget the picture... Nice track stand!"
