This week's travel blog of the week is Family on Bikes.

It is the story of a family of four's quest to cycle from Alaska to Argentina using one tandem and two single bikes. The families aim is to break a Guinness World record for the "Youngest Person to Cycle the Pan-American Highway" and a quest to bring the world to young children in classrooms as part of a non-profit organization called Reach the World. Reach the World has been linking travelling educators with classrooms across the globe since 1998.

I have been on a lot of cycling holidays in the past but never one that involved using a tandem with a "bicycle trailer" attached to the back. What I find fascinating is the tandem actually takes three people! Shouldn't it be called a "tridem"?
