While swimming the Iron Man course this morning I got a small reminder of why I don't watch shark week. While turning my head to take a breath, there right next to me (well, okay maybe 6 feet away) there was a shark. It turned out to be a 4 - 5 foot white tip reef shark. They are not aggressive. It was enough to stop me in my tracks. He was curious but didn't come closer. He was fairly close to the beginning of the course (between buoy #5 & #6). I kept seeing things at the edge of my vision for the more than 2 miles left to swim.
You don't get these stories to tell when you just do pool swimming.
