Clem7 tunnel, but of course the highlight was the timed climb of Mt Coot-tha. I didn't do too badly - I passed lots of people who were walking up! But then there were lots of exhausted people resting at the summit, and I kept riding. They'd obviously put a lot more effort in for a good time - maybe I should try harder next year!
There are photos here, password is 'qtri', search on my surname for pictures of me. There's also a slide show of images from the ride.
