I think it is 1:19:400 but not 100% positive.
It does appear after you beat silver. It’s done by sectors so I wasn’t able to see it until the 3rd sector. I ran a 1:19:3 something and was green crossing the line but I had just drifted wide in the rhythm section exit and invalidated the lap.
Ran a 1:18:4 something next lap and beat it. Sucks there is no cosmetic reward.
Edit: This game can be so fubar at times. I cleared the event beating gold but even though it gave me the gold reward it did not save my 1:18 time, still has me listed at 1:19:484 which I think does not beat gold. But no matter what once you clear the event you cannot see the gold time anymore.
