If you remove a team member from the team before the end of a challenge then they don't get the final challenge reward. They can get the interim rewards but they are minor compared to the main reward. However, the reward is always split between the maximum number of players that were in the team during the event so one thing you can do is invite team members to join before the end of the event. They might not contribute the full amount but better to let someone collect the reward than no one.

Managing a team is one of the most difficult parts of team challenges. I certainly wouldn't want the responsibility. My team has a chat group where being part of the team is as important as racing in the challenges. We've built up an etiquette about whether a team member should be in the team or not when an event starts. We don't mind carrying a few players as we have a strong team that generally makes the top 100 but also people will drop out before an event if they can't contribute and don't need the gold.
