The final not in rival mode?

Finished racing the final - took about 20 minutes. Thought it was a brilliant course. Assumed that there would be some way of racing it again and was really looking forward to trying it out with different vehicle classes. But it seems you only get one shot at it - it doesn’t seem to be included in the rival events. Or am I missing something?

I think it is a one off race, but there is a final 2 race also
