Bekele came within a few meters of breaking the marathon WR to add to his 5000 and 10000 WRs. Has anyone ever held all 3 at the same time? I'm wracking my brain rather than just googling around, and I can't recall anyone doing this. Maybe Zatopek (but I don't think so) or Nurmi (but I don't think so)? Radcliffe never had the track WRs as far as I recall. Possibly Grete Waitz?
Never done?
