I think Dibaba will do her best to slow this race down. Based on Mestawot Tufa's article about the african champs..on IAAF she went hard from 800 to win. She credited her win to Haile who insisted that she give it a shot despite running hurt. It will be interesting if she puts the hammer down and drops everyone.. but her PB is not all that.
ofcoarts the chinese may upset and Dibaba's fitness is not known... but all being equal.. dibaba is a lock for this medal.. with another ethiopian in the medals.. and maybe the chinese girl.
Deena will probably get 6,7 or 8th
