The only real vitamins I think are perhaps needed are vitamin C ( small quantities useful but large quantities shown to have a very beneficial effect ( 1000mg)) and Iron if you're low on it. My friend was really struggling with her running, got put ont iron tablets and immediately cut 3 minutes from her best 3k time for the season!
generally supplements and the like aren't needed by distance runners though!
Nothing extra than from what you should be getting from regular meals and additional ones for various medical problems. I hear cod liver oil, glucosamine and chondroitin are very good at keeping joint problems at bay though.
I think that if your eating a healthy balanced diet, including all your 5 a day and a mixture of the different food. Then you don't need any extra vitamins.
Although I always have a multi vitamin as part of my diet as i dont eat "mega" healthily, so it really depends on what else your eating.
Hope that helps
