I did the Bai Yang/Sota God Racer of Hethereau quest again for my SO's account as she said she couldn't win it. I tried it and was confused when I suddenly had a "turbo" moment. I experimented a bit and realized that you will get a massive speed boost the moment Bai Yang caught up to you, pushing you to always be at first place.
