The second I hit the water, I knew I made a mistake. There were about two hundred swimmers all diving in the lake at the same time, kicking off the first leg of our triathlon. We were indiscernible in black wetsuits and gray swim caps and kicked up so much water that you couldn’t see anything that wasn’t right next to you. My wetsuit sucked against my stomach, keeping me from taking any deeps breaths. The little air I took in was mixed with green water. I tried to hold my breath and swim underwater but the green murkiness blinded me. I could feel people swimming over the top of my legs and I knocked into someone with every stroke attempted. Panic quickly set in. Even though I was only fifty feet out, I knew I couldn’t touch—couldn’t touch, couldn’t breathe, and couldn’t see. This is how people drown.
