There are a couple of other timed road runs. Midwest Motorcycle Club hosts the Hangover Rally (https://www.midwestmc.com/hangover-rally) on New Year's Day. Team Strange hosts the I-Cycle Derby on New Year's Day also.
there used to be a bmw club organised midnight to dawn ride here in brisbane, usually me and a mate would take the z13 outfit .. was a lot of fun so i am not surprised you enjoyed yourself.
