Blizzard's official World of Warcraft website has been updated with an announcement that
a new "Spirits of Competition" event has been launched in-game. The details:
Every two years, the Spirits of Competition grow especially fervent, and draw close to the mortal realm. During such times, members of both the Alliance and Horde can honor the spirits and earn Competitor's Tabards by seeking to defeat one another in the battlegrounds. For victory in competition, they can also earn the spirits' favor in the form of a prized gold medal - and the special pet it summons.
To participate in the Spirits of Competition event, simply enter any battleground and do your best to help your team win. All participants will earn a special tabard honoring their competitive spirit. The Competitor's Tabard is a rare (blue) tabard and can be seen on the commoners proclaiming the event. For each victory, you'll also have the chance of winning a gold medal as well. You'll receive these rewards in the mail. Continue winning battlegrounds for the duration of the event to increase your chances for the gold medal.
