On Saturday 7 June 2008, in cities around the world, people riding naked to celebrate cycling and the human body.
The ride demonstrates the vulnerability of cyclists on the road.
2008 will see the third Brighton ride, following its massive success in 2007 and 2006, when over 200 people rode through the heart of the city.
It will be a morning ride, finishing around 1.30pm.
Riders will also be able to join the London ride, which now takes place the following weekend.
The plan is to set off at around 11.30am, cycle around Brighton & Hove city, and finish at Black Rock nudist beach around 1-1.30pm for a sea swim and beach picnic.
