I don't like to use "Trans-" to describe this ride as I sometimes think it is overused. Think of this ride as a loop that covers the UP that is about half the length of the Great Divide Ride
. The nice thing about this one is that it loops back to the start. You can ride it in sections (east or west) spending a 2-3 day weekend on each part. It doesn't need to be done all at once.
Someone that is traversing the UP as part of another ride could ride a combination of segments on their way across the UP as part of a Trans-UP route.
Lots of things to check out along the way.
The optional single track will tax you.
Unusual sights to see.
Fantastic riding of all types.
Stimulating wildlife encouters.
