You could try spawn limit of 2 via a class/team , the initial elim will continue from checkpoint on out of respawns change their team to an unused team (island settings on out of respawns) you could name the team “starting line” or “team select” or something then make then enter a class selector to re enter as a competing team again to complete the loop, you could even reset their class change back to a 2 lives on each checkpoint completed if you wished, I use a similar method on 4481-5841-4128 (it’s not a deathrun but the cycle is kind of the same, you have to enroll onto a team each round to participate)
