If you are the captain of your team, you can sign into your Ragnar account, go to the Team Center, and select the Team Details tab. On that tab, you will see the team name and an edit pencil that will allow you to change that team name. Every event has a Team Name Change Deadline which is listed on the Dates/Updates tab for the event.
If you wish to change the team name after that deadline please reach out to our team at email@example.com. When you reach out, please include the event you are registered to run, your current team name, and the desired new name so they can make the change. The updated name will not be printed on the bibs but can show correctly in the system.
