Picadilly Parkour

@grouser: Definitely jumping...perhaps I should've cropped wider?
I've also noted that my links which explained, are linking to my archives for some unknown reason (...aminus linking is still a mysteryto me!) so here goes:
Parkour (sometimes also abbreviated to PK) or l'art du déplacement [1] (English: the art of moving) is a physical discipline of French origin in which participants run along a route, attempting to negotiate obstacles
in the most efficient way possible, as if moving in an emergency situation, using skills such as jumping and climbing, or the more specific parkour moves. The object is to get from a Point A to a Point B using only the human body and the objects in the environment around you. The obstacles can be anything in one's environment, but parkour is often seen practiced in urban areas because of the many suitable public structures that are accessible to most people, such as buildings and rails.

Parkour practitioners are often called traceurs if male, or traceuses if female

The street entertainment was called Platform 4 http://www.xtrax.org.uk/piccadilly.php
