Last Saturday, thousands of cyclists took to the streets of London, taking part in the London leg of the World Naked Bike Ride 2016.
The mass bike ride aims to raise awareness of different issues including safety of cyclists on the road, reducing oil dependence, and saving the planet.
The nine-mile route took in various London sights and finished at Wellington Arch on Hyde Park Corner.
The annual event has taken place in London since 2004.
This year the weather wasn't great, but that didn't seem to put anyone off.
Don't own a bike? It doesn't seem to pose a barrier to bearing all and taking part. This guy apparently ran the route.
Before stopping to take some photos himself.
If you don't have a bike you could always borrow a Boris Bike Santander cycle. We suggest anyone hiring one this week gives the seat a thorough wipe before climbing aboard...
The event took place on the same day as the Queen's birthday celebrations, leading some to ride the route in royal fancy dress.
Top marks go to this particular fancy-dress get up. It's the bowtie / knee socks combo that really makes it work, we reckon.
