This is pretty simple, but one thing I have realized is that sinus problems and swimming don't mix well. For whatever reason this year my summer allergies have resulted in coughing at times and a tendency to get sporatically stuffed up. In my last race I was literraly coughing before the start. Needless to say, several times I had to come up to catch my breath and cough out half the lake. I couldn't properlly clear my nose in the water I guess and it slowed me down. I was wonder if anyone else has summer allergy/sinus problems and what they have found the best remedies to be. I'm nervous about the same thing happening again.
