Rode from 660-800 yesterday and all I can say is OMG!! The section from the Pacific to Mikes is familiar to me and last month when I rode it we had the usual great fun on super roads. All that is HISTORY! Forget what you think you know about sections. High HP, long-travel pre-runners have obliterated much of what was pretty fast and easy roads.
Silt, way more rocks and more silt await you! You will need to be fresh and steady to avoid trouble. Dont skimp on a fresh filter before and after the section!
I ride 200+ mile days with the boys but, could not wait to bail off the course and trailride after 120 miles of this. Even my 20 year old is sore this morning!
Best of luck to all and be safe.
