I have an issue that I hope someone here will have some advice about. (I wasn't sure if it should go here or in the Health Issues forum, but picked here because it's a running-specific query.) I would like to get into running, since it's a sport that requires little in the way of equipment when traveling. Plus, y'know, I have dreams of triathlons and such. The problem is, anytime I attempt to run or jog I hit a point within a quarter of a mile when my throat seems to fill with mucus. It's like post-nasal drip except it just stays there. Swallowing or drinking water doesn't do much to get rid of it.

I've mentioned this to other people (runners and not) and none of them seems to have a clue as to what I'm talking about. I've never been diagnosed with asthma or any other respiratory condition. And it's not something I face much in other activities.

When biking my throat might feel a bit congested after half an hour (sooner if it's been strenuous), but a few short swigs of water clears out my system and I can breathe again without issues for hours. When playing tennis or squash, there's periodic congestion after a while, but water helps. Swimming, hiking, and cross-country skiing are fine. It feels to me as though it has something to do with the vertical motion involved in running or racquet sports. My experience suggests the congestion might clear up over time as it does with other sports, but I simply can't keep going with that amount of mucus rattling around.

So, my questions: Does anyone know what's going on, and is there anything I can do to prevent it? Any input would be very appreciated.

Thanks!
