Elusive Targets are otherwise time limited missions in Hitman 3, that can only be played at certain times of year on vanilla servers.

However with The Peacock Project, PC players can play the elusive targets at any time and replay as much as you like. There is a guide to installing Peacock with elusive targets here: https://www.speedrun.com/hitman_3_et/guide/jeka9

Although vanilla server elusive target runs are not the focus of these leaderboards, runs will still be accepted from official servers, especially if they are currently records. If you are submitting a console run just leave a comment about it in the run description, if it matters to you.
