Help with IAAF Font

Please help me identify this font. It is used in the logo of the International Association of Athletics Federations (IAAF) and in their publications.

Thank you.


I came across this Font ID request that had no response. Well, it's only a little over one year. Anyway, the font in question is a proprietary font created for the IAAF named, appropriately IAAF Sans. It exists in at least bold and black variants. I was unable to identify the font creator(s). - Herb
