The 2.4-mile, one-loop swim course featured a very long rectangle (essentially one mile out, a short turn-around, and one mile back) with big orange buoys marking the way. Obviously swimming in the ocean presented some major differences and challenges from that which I’ve faced during Ironman Wisconsin’s Lake Mendota swim. Most notably, salt water, a one-loop course (vs. Wisconsin’s two), and no wetsuits allowed (due to the warm water temps).
I was able to get in one practice swim in the days leading up to the race. It had been years since I’d last swum in the ocean. It was an incredible experience. I felt like my senses were on overdrive. As soon as I put my head in the water, I could taste, smell, and feel the salt. And not only could I see my arms pulling through the clear, turquoise water, I could see all the way down to the bottom of the ocean! I spotted a school of beautiful yellow fish and a gigantic sea turtle. Oh my gosh, I realized—I’ve swum for 21 years, but I’ve never swum like this before. 
After finishing my practice swim (about one mile total), I was walking out of the ocean, as a woman excitedly approached me, exclaiming that we were wearing the same skin suit. Now to back up a little, a skin suit is sort of like a full-body swim suit with special hydrodynamic properties. Supposedly it provides maximum speed in the water during non-wetsuit competitions. Not wanting to be left out (nor behind!), I purchased one—the silver “Frequency” from Nineteen—a few weeks before the race. The woman proudly informed me that she calls hers the “silver bullet.” She also told me that her husband owns the wetsuit company Nineteen, which is interestingly named after “Highway 19, the Queen K on the Kona Coast,” which “represents the goals and dreams of every triathlete.” After jumping out of the water to grab her husband, she introduced me, and asked him to take a picture of us. That was fun. And I love my skin suit’s new nickname—the silver bullet. Definitely a keeper. 
So back to the race.
Without a doubt, it was the most intense, scary, chaotic, and testosterone-fueled swim I’ve ever experienced. With so many athletes at or near the same speed, there was a lot of swimming on top of each other and fighting for space. Things became particularly scary when the mob neared each orange buoy. At that point, everyone became enmeshed together, wrapped around the buoys, and shoved underwater. That’s when the kicking, pushing, and elbow throwing became most intense. At one point, my goggles were ripped off and I was hit in the face. Luckily, I was able to maneuver my goggles back on my face, but by then my eyes were stinging from salt water. 
I’ve learned not to get too upset when people become aggressive during an Ironman swim—it takes a lot of energy to get mad and to start throwing elbows back at suspected aggravators. And with such a long day, regardless of how much a little elbow action might actually be warranted, it’s really just not worth it. So I generally hold back. As hard as it might be.
At each remaining buoy, I tried to bury my head down and breathe as little as possible—so as to keep my face unexposed and avoid a bigger goggle fiasco, or worse yet, some kind of race-ending injury. By the second-half of the swim course, the field had become much more spread out. Although I never really found anyone to draft behind, and I wasn’t able to maintain my usual bi-lateral breathing (I seemed to swallow salt water everytime I tried), I did get into a very comfortable rhythm. 
At one point on the way back, I glanced down at my watch and saw that it read 50 minutes. Oh, no, I thought. I have so much farther to go to the beach, and I’m already at 50! I hadn’t really thought too much about a goal time for the swim. I knew that I’d completed all five Ironman Wiscosnin races under an hour. However, without a wetsuit, I knew my time would be slower, at least by a few minutes. But I became nervous at that point when I saw my time and realized how far out I was still from shore.
The next several minutes went by in a flash. I don’t remember much. It’s always exciting when you feel yourself getting closer and closer to the beach, and you know that you’re nearing the end of the first of three events. I like being able to check off each event. Swim. Done.
I swam until my arms hit the sand and I couldn’t swim any further. I then jumped up the stairs that led from the beach up to the transition area. They were big steps, but so much easier than running up the helix during Ironman Wisconsin! My total swim time was one hour and five minutes. 
I quickly hosed myself off with one of many green hoses hanging from the top of a tent I ran through at the entrance of the transition area. The goal was to get the salt off my body, particularly around my eyes. I continued to run through transition, and a volunteer handed me my swim-to-bike transition bag.
Volunteers then accompanied me to the women’s changing area. Amazingly there are 5,000 volunteers at the world championships for 1,800 athletes. Amazing. Although I didn’t have to change (I had my tri uniform on under my skin suit), the volunteers helped me get out of my suit, sort my gear, and put sun tan lotion on my arms and legs. I was pretty much out of it. But luckily I remembered to grab everything I needed—bike shoes, a pack of electrolytes (salt tablets), and a few extra gel packets. From there, I ran through transition and made my way to my bike. I put my bike shoes on, grabbed my bike, and ran through transition until I came to the line across which I could mount my bike. Total transition time: three minutes and twenty-eight seconds.
