I like that description: After about six hours I am usually deep inside my own head. My body takes over and my mind drifts off somewhere…a moving meditation. At night I will try and narrow my attention to a single light or glow stick on the boat or kayak. I close my eyes periodically to ‘watch’ the whole thing from above. The ‘zone’ takes some time to get into, and it doesnâ€™t last for the whole swim. Iâ€™ve never experienced anything like it during any land-based activity.â€ Via TakePart.com.
