What Causes A Bad Smell While Jogging And Rush Of Chlorine In Sinus Causing The Nose And Eyes Water?

I have noticed when I am jogging or strenuously bending over (as in yoga to wring out the organs) that a chlorine smell will come up. I most always hydrate before (during) and after the activity. Today, I was bending over and squeezing in on my gut, a rush of chlorine went into my left sinus and top of my head causing my nose and eyes to water. Before this activity I have had a full glass of water, bread, yogurt, juice, beer and coffee with milk. I used to eat a lot more and then drink large quantities to flush it out and began to notice this sensation when I was stretching. I assumed it had to do with the composition of the water.... but I wanted to include my diet this morning to see if it might also have to do with food intake.
