Crazy

That's what these guys are. They are participating in a100km up cliff and down precipice run around the Blue Mountains - "Ultra Trail Australia".

Not so crazy is the spectator sport. I don't know when I last saw so many good lookers.

They run right across a corner of our farm so a great blip opportunity.

What was really impressive was, after 46km, the number of smiles and g'days I got as they saw me photographing them.

Some would have finished after about 9 hours.
I think they have 28 hours to complete the course to avoid disqualification.
