Narrative:

Cleared for visual approach to runway xxl at ZZZ; we were turned towards the marker and were high and fast. We were able to get configured and slowed by 500 feet; but below 500 we received a GPWS terrain warning. This prompted us to execute a go-around. We entered right traffic and did a visual approach to runway xxl with an uneventful landing. After shut down at the gate; we received an advisory crew message report below 500 of vertical speed max -1456; vertical speed average -513. This is no doubt what caused the warning. As my eyes were outside at the time of the occurrence; I was not aware of the excessive vertical speed.
