The idea is to get a nice daily cycle route, just for the sake of cycling, for both leisure and fitness, cycling's a great way to relax and is also great cardiovascular excercise, better than running, which is bad for your knees over time, that and it's better because you can travel further and have more variation and sceneray changes than from running...
Step 1: Thinking about where to go.
Along with this think of ways to get there and have some recce cycles for your ideas, try new routes for a while until you find one that you really like.
Things to consider are:
*Your own fitness (start simple and build up your fitness as you go along
*Free time (If you don't have alot of it then this can hamper you, making free time is always good though)
