Air quality in San Gabriel Valley

So I’m wondering how bad it is for me to run outside for 35 minutes with the current air quality? I live in the Pasadena area and I have seen that it says it’s “unhealthy for sensitive groups” or something like this. What does that mean? How do I know if I’m a sensitive person? I don’t belong to a gym and can do my rides on my trainer, but I’d like to try and get my run in today provided that the air quality isn’t all that bad for a short period of time.

any thoughts from the ST community?
