Eduardo Chozas 6,8,6It doesn't really fit the title of the thread or the discussion so far, but on the back of Dan Martin now having not only a stage win in all three GTs, but also a top ten in each, I wondered who would be in his category here: top ten in all three, but no podium (by the definition here: I would prefer to go by results, not ceremonies for Mollema and van den Broeck).
Going back to 1970, I am surprised at how few there seem to be (though I may have missed some)
7,3,8 Van den Broeck
5, 8,8 Fuchs
Did I miss anyone?
