Once again, I found myself forced to the ground, not able to breath. Thanks to me forgetting my inhaler and the extremely high humidity at the Sunburst Showdown in WI. I was comfortably riding about 15th and looking to move up when the climb (very humid area) the second lap had me off the bike gasping. I continued. After the mowed single track (very humid area), it hit again with a vengeance; dizzy, weak, almost passing out. After many minutes I got up and limped into the finish to DNF when I got hit again. Forced to lay in shade, on a concrete slab, gasping uncontrollably, had me wondering if things like the Arrowhead are a good idea.
