This morning I had a great run, really hard uphill most of the way. After my run I went for a bike ride. I really pushed myself hard today because we have finally had a cool morning, and it just felt good. After my bike ride I noticed I could smell ammonia, and not just a little, for about 15-20 minutes it was really strong! I have noticed this before but not as much as I did today. What is the ammonia smell all about and is it normal?

I just had a full metabolic panel done and my magnesium checked two days ago. I do this because my potassium usually gets pretty low so I have it checked from time to time. My sodium and potassium were a little on the low side but everything else was normal. So, what does the ammonia smell mean? Any explanations would be helpful!
