Did something stupid: Swam a 1,000-meters moderately hard in 84-degree water
Did an experiment with Fran Crippen in mind. I went to L.A. Fitness and did a moderately hard 1,000-meters in a very warm pool. The result was ugly. During the whole swim I felt like I was swimming at higher altitude and my heart zoomed 20% faster than normal. When I finished the set my heart rate was 160-BPM and took much longer than usual to slow down. It has hovered around 92-beats a minutes for the past hour.
At the 500-meter mark the water inside my cap felt hot. My goggles were fogging badly and on my last 100-meters, which was a build into a sprint, I felt as if I had swam 3,000-meters.
This experiment was conducted at an indoor pool with an ambient air-temp in the low 70s. Fran Crippen was swimming in water that near 90-degrees Fahrenheit with 100-plus-degree air temps. All I can say is that the only people who can appreciate how dangerous open water swimming in hot water is are the open water swimmers and they seemingly have had no say on where and in what conditions they swim.
Heart rate is now 90-beats-a-minute some one-hour-and-twenty-minutes later and I am mot happy.
