Folwren: in post # 262 you'll want to be picking either the West Emnet or East Emnet; I don't think Tolkien ever gave a clue as to which of the two was first.
Firefoot: in post #263 there was no voice-amplifying sound system, so I don't think an announcer would have been heard during the actual race.
As to Eodwine and Saeryn, I'm waiting for a post from Celuien before I make one myself.
