That's a significant challenge for a newbie. But it won't take that long to get accustom to whatever bike you ultimately end up on, There are just so many options for routes. If you enter Texas in Texarkana and ride diagonally to El Paso, you'll be right in line to hit Tombstone and on into Cali where you can take that long road on up to Washington, then figure out how you might want to hit Utah. Except for Utah, I've done that kind of route so many times it's boring now. It's a lot of riding so I hope you are physically fit as you'll find out, it's needed. Some bikes more than others.
