Looks like the course is going down the long rocky downhill between Hwy 3 and Laguna Salada that was used by the recent NORRA/CODE race. That is going to be extremely challenging for the bikes that will be running that section in the dark. It's very rocky, very tight, lots of turns with steep drop-offs, and its a long frickin' downhill stretch.
Could turn into a real bottleneck situation for the cars/trucks later...
