2007 Olympics in Munich

As part of an employee motivation movement, one of the largest worldwide energy groups had nearly 900 employees from 13 nations, compete in 20 sports disciplines for an Olympics weekend extravaganza. The memorable event took place in the 1972 Munich Olympics Stadium and various other sports venues around the Bavarian capital. 

Best summarized by one of the many E.ON employee-thank you's we received after the event -

"Probably the best corporate event I have ever attended, Just first class!
It was a true life experience as I have never participated in anything like it in my life – amazing!"
