This is a fine little production, and it reminds me alot of 'Trigger Happy TV'; here is a playlist of 12 different "urban sports" enacted and created by Balls of Steel that I happened to come across. 
I recommend watching 
Urban Sprinting, 
Keep em Out, 
Burger Bowl Off, & 
Big Euro Stranger Rodeo. The rest are ridiculous and maybe a good premise for a prank, but are not as funny as they would be if you experienced them for yourself.
