Hi all, I am a new runner, I have ran about a 100 KM last 6 weeks but I have faced a problem. whenever I run no matter the time of day I run in there is always a strong smell of old car exhaust fumes. It's so bad that whenever I finish a run no matter how short (15 minutes) I always get a strong car exhaust taste in my mouth. And that can't be good for my lungs, right? So I wonder if any of you guys have faced the same problem and what was your solution for it. Would a mask work? is it even a problem or should I just ignore it? thanks in advance
