23:59 in race?

Hoping someone can help. Did my first race on Zwift today. Took 1:32 but was given 23:59.59 in the results to come last! Bit gutted. Any reason for this? I hadn’t registered with Zwift Power before the race, but have now. Wasn’t sure if that was why.
Thanks for any help you can give me.

That usually happen if you join late.

Ah right. Didn’t think I did start late but it was my first time so may have done without realising. Thanks for the reply.

Good luck on your next race. It is a lot of fun.
