Meanwhile her competitors were rested and focused on this one race, anticipating Hassan's kick as a factor they needed to beat.
Defending champion Letesenbet Gidey succeeded last year, winning by hundredths of a second as all the medalists held off Hassan.
With eleven laps to go, Agnes Jebet Ngetich led the Kenyan team to the front, with the Ethiopian contingent marking the move, then Gudaf Tsegay took them forward.
They continued to accelerate through the bell, with Hassan running around the field from tenth to first during the penultimate turn.
Gidey walked back to give her a high five and a hug as she crossed the finish in eleventh place.
