So, you already know by now that my day at Ultratrail Australia wasn't a miraculous victory. That's OK.
I wasn't in a great place mentally when I posted my race preview. Things improved overnight, and by the time I got to the start line I felt confident enough for it to be an each way bet as to whether I'd cross the finish line victorious or pull out at the 4k mark, where the course passes back by the start line after an out and back through Katoomba.
