Oh and I replace my trainers every 6 months (which is annoying, luckily I know the girl who sells me the shoes well enough to get a discount) and have a neutral shoe - i.e. one that does not correct any pronation. I have a custom made insole from a specialist to do the correcting.
And good point by andygates regarding tarmac, attempt to keep clear! Oh and with stretching and cycling.... ensure you stretch those calfs out after, especially if you do running aswell. Because cycling and running try and build the calf in different ways, if you do not stretch you may find yourself cramping badly while running - I can speak with personaly experience with this one aswell, having suffered cramps recently while long distance running, whereas I was fine before I began cycling.
