Les 24h Vélib

Celebrating the 7th anniversary of the Parisian Vélib system. A stretch of the Champs-Élysées are closed for the traffic and a Vélib roundcircle is installed. In the background the one for adults, in the foreground the one for future Tour de France participants.

There are some 400 bikes at free disposal. People participating bring their power, can choose one of three charities and each round pedalled will contribute (although I didn't find out who pays then - probably some main sponsors).
