20 DAYS!!! So how do you know when you're ready to take on a cross-country bike trip?1.) When spandex becomes your outfit of choice and regular cloths just don't seem right.2.) When you've worked up an appetite for PB&J everyday.3.) When you've mastered opening up a Clif-bar while riding, and on-the-road hydration.4.) When changing a flat is no longer a question of if you can, but rather a game of who can do it faster. ( My personal best is still 13:25)5.) When you've trained right through the inner lining of your tires.Turns out as of yesterday I've reached #5. To be fair though those old tires did have some previous pre-training miles on them, but on my last ride it became pretty obvious it was time to swap them out. With a new set of tires on, and that new tire smell too, I think I'm just about ready to go. I can't wait to meet up with my fellow I4K -ers and start this adventure. It'll be great to meet so many new faces along this journey.
