n race day, UltraSignup replaces the entrants list with a results page. The registrant list is just gone.
For evening events, that’s a problem. Runners showing up hours before the start want to confirm they’re registered. They’re not searching their inbox. They’re going to the race page. When the list isn’t there, they panic and email the race director.
Don’t replace the entrants list with results. Keep it visible through race day and post results separately when they’re ready. The data is already there.
