There was only 1 race for lvl 100 but for hardcore. The first 1000 players reached a hardcore lvl 100 got their name on the lillith stattue irl.
But thats it. The race is over. Names are on the stattue. If you didnt made it back then. Accept it. There is no further racing. Even if you want to believe there is one. To make the lost race at release a bit painless.
