Fast runner from east of Germany with money to burn (7)

I believe the answer is:

ostrich

I'm a little stuck... Click here to teach me more about this clue!

'fast runner' is the definition.
'ostrich' can be an answer for 'runner' (I've seen this before). I'm not certain of the 'fast' bit.

'east of germany with money to burn' is the wordplay.
'east of germany' becomes 'ost' ('east' in German).
'with money to burn' becomes 'rich' (I've seen this in another clue).
'ost'+'rich'='OSTRICH'

'from' acts as a link.

Can you help me to learn more?

(Other definitions for ostrich that I've seen before include "Creature" , "Person refusing to face reality" , "He ignores the truth" , "Large flightless bird of Africa" , "non-flyer?" .)
