Omnium and yachting are good ideas, I like those (although the spelling of yachting is wrong - it's a strange word. Pentathlon is misspelled too.)
I like to amuse myself by trying to find something starting with the impossible letters. Underwater swimming was an event in the 1900 games, so that would have been possible for U.
Yatching is not a sport in olympics
Never heard of Omnium

How about athletics?
