In the recent years the air quality in my city have been rising to alarming levels especially pm10 and pm2.5, but this last months the daily average have been over the WHO limits by a fair amount (around 100 pm10 24hr-mean), to the point where exercising outside could be considered unhealthy and dangerous. To others that have gone through similar situations what have you done? I have the option of driving 1-1.5hr on weekends to remote country roads to more clean air, but I feel that I would only be contributing to the problem by unnecesarry driving (the main cause of increase pollution), doing most if not all my training indoors it's another alternative but i'm not that keen about that since I do enjoy being outdoors.
