A student has described how she saw a cyclist – complete with helmet – having sex in some bushes on a common in southwest London.

University of Roehampton English Literature and Philosophy student Sian Carpenter was travelling along Putney Commondale on Monday afternoon when she spotted the amorous couple.

> Team Sky reported to have tested whether Viagra helps riders' endurance

The 21-year-old told The Sun: “I was on a bus going past Commondale and I saw a cyclist only slightly behind the trees, in the full get up – even his helmet.

“So obviously I’m thinking ‘what’s he doing there’ so I glanced over and that’s when I saw the other person in front of him and the penny dropped.

“It was so funny. I doubted if that was what actually was happening though, then another person on the bus reacted and turned round really shocked so then I knew I was right.

She added: “What was weird to me was that the other person was just dressed normally in a coat – I don’t know how it would have happened.”

We don’t know either – but it has got us wondering whether Team Sky are still testing out the performance-enhancing benefits of Viagra and, if so, which of its riders might have been training in the area yesterday?

Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.
