Another thought I had since you mentioned riding the gorge both ways was wind. The winds in the gorge are strong. Riding both directions means that you'll likely have a tailwind one way and fierce headwind the other. Winds can be from the west, or from the east and really strong. Be prepared for this.
This map is in sections, so scroll down to see each section

Yes thanks for the warning on the winds. I was already aware. I was already planning on keeping days fairly short. I was not aware that it was so unpredictable so thanks for that. I was hoping the prevailing wind was one direction or the other. Ot would make planning so much easier.
