Loving the beard jokes! So true....
Randonneuring is called Audax in Australia too as I understand it. When I started cycling fairly often I was keen to get into Audax riding. I did 100 and 150 km rides with the local group here, which were quite enjoyable.
I started a 200km, and got about 100km in and found myself alone. That was when I realised that I was bored and my bum hurt. It was then that I decided to give crit racing a go and I never really looked back!
Have a lot of respect for cyclists that can do 200+ km rides, especially when done solo. Takes a special type of mental toughness.
