Depends on if your goal is too pr in them or just have fun running them.  Clearly you could run both but if you want a serious pr attempt you should pick the most favorable for that.  You could likely still do both and try for a pr but you would have to decide which one was the pr attempt going to be on and take the other one very easy.

 

I have done races 3 weeks in a row knowing the third would not be my best race ever.

True, I'll have to wait until I know the Evansville's date to decide if I am going to register for that as well. Either way, I actually have another race 2 weeks after the Annual Indy Half, and it's up in Indy too. Even if I don't run the Evansville Half on October 6 or 13, I'll still be running the 18th Annual Indy Half on October 19 and the Indianapolis Monumental Half on November 2.
