Hi everyone,
I am a fairly fit rider who can ride 150 miles in a day without much trouble. My wife is a full time student and she can ride over 50 miles by herself but under no circumstances could she ride 150.
We are car free now (by choice) and our family lives about 150 miles away. We have the perfect opportunity to travel there by bike because the katy trail (missouri) can get us 100 miles of the way there.
How fit would my wife have to get before we could ride that distance on a tandem and it not end our marriage?

Should I expect her to ride a century by herself before we do this?
I could carry quite a bit of the load but I cant pedal both us all the entire 150 I'm sure.
Any guesses? If it helps I am 5'9 and 155# and the wife is 5'1 and 105#.
I realize that we would need to practice on the tandem quite a bit first.
