Saw this on Twitter, and it appears the Ethiopian federation has changed course on not allowing athletes to double, and their team probably just got even better.
Some of the changes:
Letesenbet Gidey and Ejgayehu Taye doubling 5000 and 10000m
Hirut Meshesha doubling 8/1500m
Dawit Seyoum on 5000m team
Tadesse Lemi replaces Melese Nberet in 1500m.
Berihu Aregawi and Selemon Barega doubling 5000 and 10000m (Tilahun Haile and Milkesa Mengesha reserves now)
Also strong marathon teams confirmed.
