Azeroth Grand Prix

"Legends speak of a hidden race track north of the border where representatives from the far reaches of the land gather to test their skills and racing prowess. This event is known to break even the mightiest of combatants with its no-rules-barred arena."

The Azeroth Grand Prix is a racing event held somewhere in Azeroth.

Players could choose between Diablo, an orc, a lich, or dwarf riding vehicles in around a race track in the official Blizzard scenario for Warcraft III called Azeroth Grand Prix. The event was hosted on a track that had varying climates and obstacles. Some of the track was on a frozen lake, causing slips. Some of the track was next to a volcano which spewed lava at the racers. Some of the track was next to tornadoes which threatened to blow the racers in the air. Another part of the track had a magic caravan crossing.

Racers could limit the other racers in a variety of ways. Racers shot bullets at racers in their front. There were also various present boxes on the track that held advantageous items. One item made the racer's exhaust spew fire. Another set a landmine. Another made the racer ethereal, limiting damage on him. Another shot a frost cloud in front of the racer.

Stopping in a pit stop was advantageous for the racer. The pit stop was a sidetrack at the start of the race where the racer's vehicle was repaired.

This could be the Mirage Raceway located in the Thousand Needles, although it is not clear what "north of the border" refers to.
