If I can remember my PE it can depend on the type of legs you have - i.e. how muscled they are, sprinters or grimpeurs legs? As David says your hamstrings are shortened with cycling but you also develop the muscle above your knee. When running it can be painful as this now developed muscle tends to get a bit of a bashing. I think cycling does develop your muscles in quite a specific way that doesn't tend to lend itself to crossing over in to other sports, although the triathletes out there must have to get round this and can probably shed more light.
