That "flat track raceway" is called Wirewmold; and yes, you are allowed to bend it:
Is a bender available for the 500 and 700 series raceways?
The 600B Bender is used to make bends, saddles and offsets in the 500 and 700 series raceways.
...and you can buy one for $69.90 here: http://www.electricsupplyonline.com/prod/wiremold/600b_w003980.php
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.
