firstly welcome in advance,
The cost of chicken, plucked and ready to go is very cheap, in Carrafour they sell 2 small chickens for just a few QR
I always fly either Qatar air or Etihad and have always found them excellent although I sway towards Etihad, just a personal preference though.
As for running, I don't think August is the climate for running, the humidity will kill you, best to try and find a nice air conditioned gym where you can run to your hearts content.
hope this helps, x
