To Double or Not?

I haven't heard of a decisions as to Tirunesh running in the 5,000 M. Doing a double is not easy. The dominant Kenenisa never managed to do it in two tries. But Tirunesh has been there and done that. In the 2005 WC she did the double beating Berhane Adere and Mesert Defar. My guess is that she will go for it. It won't be easy running against a rested Meseret.

Here are some of my thoughts that come to mind when weighing if she should or should not.

Pros:

• Tirunesh Dibaba proved she was in great shape. Looked like she could sprint another lap.
  
• She must be brimming with confidence.
  
• Her 5, 000 M WC in June means she may be even better at the 5,000 (scary)
• The runner that would be displaced, Belaynesh Fekadu, is not a medal threat.
• She is a sure thing to medal.
  

Cons:

• She ran a super fast 10,000 M and may not recover fast enough - slow performance.
• Too many races in a short time increases the risk for injury.
  
• Belayanesh Fekadu only 21, is on an up swing and will miss out an opportunity.

Any opinions?
