Great ride, report and pics. I do not think one can design a tougher ride on the Peninsula than that one. The climbing is just incredible but worth the effort for the scenery. You guys have certainly jumped into tandem riding taking on the most difficult climbs / rides.

You guys should think about the Everest Challenge. You have plenty of time to train for it. http://www.everestchallenge.com/Ever...lengeBible.htm

It is in September and you could do it on the tandem.
