I see alot of dead things on the road when I do these early morning rides. Raccoons, possums, deer. Reminds of the mortality of human life and how I could become road kill in an instant if I get tapped by a car. At least on the trails, probably the worst I could is hit a tree or loose it on a nasty downhill. I'd probably still walk away in better shape than if I were to have gotten plowed by a car that weighs close to a ton.
What I am doing cannot technically be called "training" because I am not doing any type of structured training plan - I just go out and ride. It's good and it's bad. It's good because it gives me a lot of freedom to just do whatever the hell I want, when I want. It's bad because I am probably not maximizing the time I am actually spending on the bike.
