I am in training for a marathon and when I am on vacation in Playa del Carmen, I need to run 16 miles. I am a female also. Is it safe to run. Are there any trails. I can take the bus somewhere and run back to Playa if that is safe. Can anyone give me some suggestions of a good running route. I suppose I will have to worry about stray dogs also. Would mace be the best thing or just a stick?
