Michendorf wasn't the only place to host a Nikolauslauf – Cologne and Tübingen were among others to put on runs, but did not insist on participants wearing the costumes.
The Tübingen Nikolauslauf half marathon has been going since 1976, and this year 2,662 runners crossed the finish line, according to the event website.
