That "flat track raceway" is called Wirewmold; and yes, you are allowed to bend it:
Question:
Is a bender available for the 500 and 700 series raceways?
Answer:
The 600B Bender is used to make bends, saddles and offsets in the 500 and 700 series raceways.

you could carefully use a 1/2" EMT bender - BUT, as EMT is round and wiremold is square your results may vary and the wiremold will more than likely show the tell-tale marks of an EMT bender having been used.
