Thank you. This is a great tip. I am training for my first half marathon and I've been running really early in the morning before work or after (around 6pm), but sometimes it gets too hot or I can't make those times and end up running around 11am on weekends. Yesterday was the worst I ever felt. Do you know how accurate areavibes.com is? I'm trying to move to a city with cleaner air within the incorporated or unincorporated LA area. Thanks again for the suggestions! I will have to check them out!
