He can't win the polka dot. There's only three Cat 4 climbs left in the entire race, offering a grand total of 3 points. Vingegaard has an 8 point lead over Geschke, and 13 point lead over WVA.
In 1969 Merckx won the GC, the KoM and the Points competitions. And six stages.
Re: WvA being on for spots and green - anyone else done that? Merckx I’d guess.
