Usage tips
Compound word
'Rennbahn' is a compound noun made up of 'das Rennen' (the race) and 'die Bahn' (the track). So it literally means a 'track for races'.
EXAMPLE
Die neue Rennbahn wurde speziell für Formel-1-Autos gebaut.
The new racetrack was built especially for Formula 1 cars.
Word family 'Renn-'
The word element 'Renn-' is used for many words related to speed and competition. When you see 'Renn-', it often has to do with racing, as in 'Rennauto' (race car), 'Rennpferd' (racehorse), or 'Rennfahrer' (race car driver).
EXAMPLE
Sein größter Traum war es, ein berühmter Rennfahrer zu werden.
His biggest dream was to become a famous race car driver.
Correct preposition

EXAMPLE
Wir fahren am Wochenende auf die Rennbahn.

Rennbahn vs Bahn
train / track
'die Bahn' and 'die Rennbahn' can both mean a marked-off track for sports or competition. 'Bahn' is more general and can be a single lane, for example in running, swimming, or bowling. 'Rennbahn' is more specific: races take place there, often with horses, cars, motorcycles, or dogs. The words can be confused because a 'Rennbahn' is also a kind of 'Bahn'. But 'Rennbahn' is only used when the purpose really is a race. For normal sports lanes or tracks, 'Bahn' is the more suitable word.
