base miles base miles base....
UK,
Each individual day on ALC is hard, although there are lots harder rides: Devil Mountain Double, Death Ride ...we could go on an on. You'll need to climb and descend well but I feel the hard thing about ALC is the back-to-backness. Get up, do a century, repeat 7 times.
IMHO for now and the next few months keep building a base of base miles, core fitness, weight lift and or Pilates/Yoga. Tell your trainer there what your goal is so they could specify what will build leg strength. The climbing will come.
good article for you here:

Can you come over here for a month or more before the ride? We've got hills in the East Bay that'll more than get you ready.
