On Sunday 21 September 2008, at the Samsung Super League Final in Barcelona, Beerbaum was a member of the winning German Nations Cup team.

[1] In the Final, he rode the nine-year-old Westphalian gelding, All Inclusive NRW to a double clear round, and was one of only two riders to do so, his teammate Marco Kutscher being the other.

At the 2004 Olympic Games, Beerbaum and his mount, Goldfever, managed to finish with only 4 penalty points, helping Germany earn the team gold medal.

The International Equestrian Federation found Beerbaum guilty of breaking the rules, stripping both him and his German team of their gold medals, dropping Germany down to bronze.

After the hearing took place, they ruled that Germany's stripped gold medal was then given to the Americans and the silver to the Swedish show jumping team.
