"Giro" is "tour" in the sense of Tour de France - a race circuit - in Italian. It can mean other things (turn, lap, period, rounds), but in context, I think this is the correct sense.
"Galoppo" is "gallop" in Italian.
Giro Galoppo is therefore a "Galloping Race" / "Race at a Gallop" / "Gallop Race/Tour" or very literally "Tour Gallop".
