State that's stunned to host our excellent sporting event (4,2,6)
I believe the answer is:
tour de france
'sporting event' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tour de france that I've seen before include "Famous cycle race" , "Professional cycle road race" , "Tuned for race (anag) - a cycle race" , "sporting event" , "Major bike race" .)
