This morning I was running and about half a mile into my lungs were screaming. After about a mile I had to stop and walk the rest of the way due to lack of oxygen to lungs, brain and feet. I started running again in anticipation of the Honolulu marathon and have been going 3-4 miles every morning without any problem, so this sudden OMG-I-can’t-breath! thing going on, not cool and not usual (at least here in Hawaii; in Washington, Texas and California it’s normal due to whatever’s in the air). My only guess is the vog (volcanic fog) is out or something. BEWARE!
