Updated list with a South African flavour.
I used to do morning & weekend training rides with Tony Impey & his teenage son Daryl. Tony kindly sponsored me with his team kit so I guess I can boast that at one time, back in the day, I was on the same team as a current GreenEdge pro.

Still not as prestigious in these parts as saying I know Mick Curran though!
