What size are they? How tall are you?
You don't need a heavy trailer to train.
What you need is many 60/75 mile rides to build endurance.
I would also ask what is your pants inseam length?
I have seen reference to someone that races cyclocross with 205mm crankarms, but he is really tall.
For a long tour, try to get used to staying in the saddle to pedal hard by gearing down instead of standing on the pedals. I used to stand to accelerate from stops and to power up short hills, but my knees have objected too much so I stay in the saddle now.
