Another option is the DIY more-or-less metric out-and-back to the Junction. You get all the scenery of Del Puerto Canyon without doing a full 100mi. it also tends to be much less windy than the official 100k route. The climb back out of the Junction is not a big deal - it is much easier than the climb out of Del Puerto to the drop to the Junction. As I recall. it is a little short of 100k, but you can ride towards Mt. Hamilton a little way (easy and pretty riding) to fill it out.
