I second that Sue... I think you are definitely ready for a century. That Peninsula one has a ton of climbing, a little bit too much for me at this point, or else I would join you I don't think I'm quite ready for a century yet. Maybe one that was flat, like <3,000 feet. But that's unlikely to find something like that. A few more long distance rides though, and I think I'll be there. They say if you can do 75% of a given ride in your training, than you're ready for the real thing, right?
