Lots of people select a route, for example, The Atlantic Coast Route or the Southern Tier and ride that. The "route" is what they are riding.
The US stage of this little adventure was about visiting places I wanted to visit - the cycling just happened to link them together.
If I had set out to cycle the Atlantic coast route I could well have aborted it once I discovered the reality of the roads suggested.
I'd easily imagine that if I had no particular grá for Texas the highways recently passed and the ones to come (if I continued west) would also be testing.
I'm glad that I chose places I wanted to visit first, then organised to cycle between them rather than selecting a route and then trying to figure out what's interesting along it.
The fact of having regular destinations with different attractions was a great motivator and balm in times of discomfort.
Honestly, if I had three months to cycle coast to coast and all I had to focus on was the arrival on the other side I'd probably become a little crazier than I already am. Just the mental focus of "getting to the end" would probably tip the balance away from being able to stop and smell the roses.
I'm of the opinion that just about anyone can bike tour on just about any bike. People tend to focus on gearing, weight, ascents etc and neglect the mental gearing, mental & emotional weight we're lugging around and the mental & emotional rollercoaster we can ride on a tour. When we get the balance right between physical, bike & gear and mental preparation we can really enjoy ourselves!
Now I've to go & cross a border!
