Usage tips
Compound word
The word is a clear compound of 'das Rennen' (the race) and 'die Strecke' (the route/track). So it literally means a track on which races take place.
EXAMPLE
Für das Radrennen wurde eine spezielle Strecke durch die Stadt gesperrt.
For the bicycle race, a special route through the city was closed off.
Correct preposition
To describe an activity or a location, you use 'auf der Rennstrecke' (on/at the race track). Movement toward this place is often expressed with 'an die Rennstrecke' (to the race track).
EXAMPLE
Die Fahrer trainieren auf der neuen Rennstrecke.
The drivers are training on the new race track.
Typical collocations
Common combinations are 'auf einer Rennstrecke fahren' (to drive on a race track) or 'trainieren' (to train). Adjectives that are often used are 'berühmt' (famous), 'modern' (modern), or 'anspruchsvoll' (challenging).
EXAMPLE
Er träumt davon, einmal auf einer berühmten Rennstrecke zu fahren.
He dreams of driving on a famous race track one day.

Rennstrecke vs Bahn
train / track
'die Bahn' and 'die Rennstrecke' can both mean a defined track or route on which you move or do sport. But 'Bahn' is much more general. In swimming, running, or skittles, a 'Bahn' is often just a single lane or area. 'Rennstrecke' means a special track for races, often for cars, motorcycles, horses, or similar competitions. The words can be confused because both have to do with sport and movement. When it is about a single lane, 'Bahn' usually fits. When a race takes place on a track built for that purpose, 'Rennstrecke' is more precise.
Rennstrecke
Die Fahrer testen ihre Autos heute auf der neuen Rennstrecke.
The drivers are testing their cars on the new race track today.
Bahn
Im Schwimmbad war nur noch eine Bahn frei.
There was only one lane left free at the swimming pool.
