McMillian says she should be capable of 29:34 which seems too fast for Mary. With some 10000m training I think she could/would push the pace for around 29:50-29:58 and medal.
Mary Keitany is doing just what she is very good at. Why anyone would want her to move back to 10000m? All these times about sub 30 min is all in theory and in your dreaming computers!!! We have Lineth Masai who is capable of 29:40-29:50 legit. And can challenge for gold not just to medal. Vivian Cheruiyot has the same capability if she shifts her focus more towards 10,000m. Mary Keitany has shown better consistency in the half marathon than any Kenyan woman before and hope she will master the marathon in the like manner. That gives us(Kenyans) a chance to win gold in the marathon in the coming world champs and Olympics next year while at the same time have a chance at winning 5,000m and 10,000m .
