MTB (tech session at Ourimbah) 2:00:00 
Rode with Garry Millburn at Ourimbah with view of fine-tuning shocks. Spent about an hour on a little secret pump track, which was great for technical skills practice especially cornerning.
Discovered to my dismay that I have been riding with my chain off the jockey wheel at bottom of hanger since chain ring issues occurred on Saturday. Given that I must have ridden for several hours in that state on Saturday carbon cage is now paper thin. Something to keep an eye out for at Worlds! Bike felt a lot faster after putting the chain back into place, but kept falling off continuously which was a bit of a pain.
Achilles fine again today.
