Go swimming in a natural body of water.

“During a few seconds, I was (finally!) one. I wasn’t in the past, I wasn’t in the future, I wasn’t judging, I wasn’t thinking, I was just one with the experience. It’s like a super enhanced version of ‘the zone’, as we endurance athletes call it. [...] Every tentative of taking over by my jittery mind was vain, the cold water was forcing me to be completely immersed (pun intended) in the here and now.”

“I walked over to the lake, but this time I did not cry. I just told myself that I was going to conquer the swim. I was once again in the last wave and took my time getting into the water. Being the last wave and last one on the swim course, I had the luxury of having a kayak follow me all the way in. When I finished an hour later, my daughter and coach were there cheering me on.”
