People in the Tour de France, for example (4)
I believe the answer is:
race
I believe this clue is a double definition.
'people' is the first definition.
(people can mean a national group or race)
'tour de france for example' is the second definition.
(the Tour de France is a race)
'in the' acts as a link.
(Other definitions for race that I've seen before include "Rush" , "Care about contest" , "Run fast" , "Rapid current" , "Run, dash" .)
