Car company beginning to organise athletic event, ignoring university records (5,5)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

AUDI (German car manufacturer) + beginning letter of O [rganise] + DISC [u] S (an event in field athletics), without the U (abbreviation for university). Is this really a phrase? Perhaps as a retronym to distinguish “compact discs containing music” from other uses of the CD format such as DVDs or data storage – but I’d probably call them “audio CDs” if I needed a phrase for them.
