5k/10k/HM road races in Barcelona?

Hi all! I'm a non-Spanish person who will be living in Barcelona for from late August to November 10. As an avid runner, I'd really like to compete in some road races while I'm there to experience more of the area and also just to have some good experiences. Unfortunately, I'm trying to research what good road races are being held during my stay, and there's a lot of Spanish-language stuff I'm having some difficulty sifting through. Would anyone have anything to recommend? I was looking at the Gandia Half Marathon as well as the San Sebastian Half (which seems to be running out of spots soon...?) but am wondering if there are any other alternatives that are closer to Barcelona. Also, has anyone participated in these, and how were your experiences?

Thanks so much!
