Bolt took his first shot at success on the world stage at the 2002 World Junior Championships in Kingston, Jamaica, when/where he won the 200-meter dash.

Should we use when or where in this sentence?
Thanks a lot : )

Where should be used here; the focus is on the event (the 2002 World Junior Championships), rather than the time period. Had the event and location been omitted, and only the time given (“Bolt took his first shot at success in 2002, ...”), when would be used, as the focus now becomes the time period.
