The Dragonflight 10.2.5 Seeds of Renewal introduced the Outland Cup Circuit which added Dragonriding challenges throughout Outland. Though the questline only has two quests, the whole thing will take you no less than 40 minutes to complete. For each challenge completed, you will receive a Riders of Azeroth Badge (currency) to purchase a unique Transmog Set themed after the Dragonriding Cup Circuit.
The transmog set is named Outlandish Drake Racer’s Silks. The transmog item and prices may be seen at the end of the second video — titled: The Outland Cup Circuit.
