Oh, and you'll need to find a road too. road cycling is no fun without it.

eggbeaters are fine if the soles of your shoes are stiff enough, and you can certainly start out in your MTB shoes. i don't get any problems with mine on rides >100km unless there's a lot of climbing (but then i'd get sore feet on my older Look pedals too)

think about cars! they hurt, and often the drivers can be real pricks. don't fight them, they Will win. just listen and avoid unitl you get more confident.

enjoy
