Urbanathlon or Powerrace?

Bought my October copy of Men's Health Philippines today and found out that the annual MH Urbanathlon coincides with the New Balance Powerrace. The 2 runs are among my favorite road races so I am torn between which event to join. Of the many weekends, why did both events choose to be on the same day? Well, I'm sure they didn't plan this. And I don't think either will change their dates. Oh well, guess I'll just have to flip (a coin that is) for it.
