Kastenlauf (literally beer crate-running) or Bier-Rallye, is a drinking game that is played in Austria, Germany and Switzerland.
It is a race among teams that consist of at least two people carrying a crate of beer, the contents of which must be consumed prior to crossing the finish line.
As no application was submitted for the Harassenlauf in 2010, the canton of Baselland and the municipality of Münchenstein declared the event illegal.
As the initiators and fans called for participation on internet forums and social media, the police responded with a large contingent.
Apart from minor provocations and skirmishes, the confrontation between the law enforcement officers and the mostly young Harassenlauf participants was peaceful.
