Sprint - ?? - Oly

Since 1998 I've done the Rocketman 5 or 6 times.  The race used to be called a sprint and was 1/2 mile swim/12 mile bike/5k run.  Last year they changed the distances to 800-m swim/33-k bike/7.5-k run.

The website says this:

The new distances should prove a great stepping stone from sprint to Olympic triathlon distance. Rocketman is a USAT sanctioned race.

So if this is a 'steppng stone' from spring to Oly, what is it called?  Half Oly?  HO?  :-)  Or is the 'rule' anything shorter than an Oly is call a sprint?
