A good friend of ours is turning 65 this spring, and wants us to do an imperial century (with 8000+ feet of vertical) in Mallorca at the end of April to celebrate.

There's a good chance the weather at home could prevent us from riding outside before we arrive a week before the event (roads were snow covered and icy well into April last year.)

We plan on snowshoeing, yoga/core work, and x-country skiing (we're beginners) along with as much trainer time as we can stand (have managed 3+ hours in the past - not that I'd recommend it;-)

Going somewhere else to prepare is probably not an option, and this will be on a tandem as my wife's balance issues preclude the use of half-bikes;-)

Over all fitness is pretty good,and we've been tandeming 2000+Kms for the last 10 years, including lots of vertical.

Any thoughts on what else we can do to get ready?
