Looking for something interesting to do for a couple of hours yesterday, I discovered that the 2009 Australian National Mountain Bike (MTB) Championships were on here in Canberra, at Stromlo Forest Park.
The guys (and girls) who do this, especially the downhill, have got to be crazy. Not in a million years would I charge down a hill over rocks and shit at 70 km/h!

they ride on shit? ;o)
you did a great job getting photos actually in focus!
You need some serious balls for this, I tried it once… All I can say is that it didn’t end well.
