Nations following broadcast events (5,5)

I believe the answer is:

relay races

'events' is the definition.
(relay race is a kind of event)

'nations following broadcast' is the wordplay.
'nations' becomes 'races'.
'following' says to put letters next to each other.
'broadcast' becomes 'relay' (I've seen this before).
'races' put after 'relay' is 'RELAY RACES'.

I've seen this clue in The Times.
