i believe this can be done on multiple races but i did it on clearance level 4, then selected Italy Showdown, it is a hunter race. once started just drive near walls and you will see lots of fruit stands, just drive through ten of them and you are good.
*once you select a clearance level then select a race, the mission brief pops up and in the top right corner it will say what track it is, so that is where you look for italy arena if you were going to do this on a different clearance level.
