I think since I've done some freakishly long rides - Central Coast at 209 miles! - I just kinda figure, what the heck. I know how to fuel myself and what works and where to keep my heart rate. I know things will hurt. It's just a question of how much and what. I don't think it will be my back. I've had two months of consistent core work.

I'm worried about the saddle time and its effects. I'm hoping for 15 hours or less.

Here's the route with an elevation profile at the bottom. None of the climbs are more than 800 feet. It looks like it's actually about 188 miles.
