As part of the final preparation for my upcoming Swim to the Moon 10K in Michigan, I did a “dress rehearsal” at Parker Canyon Lake on Friday, July 27. The goal of the swim was to do a full 10K (6.2 miles), with deep water stops to take gels (Accel key lime are my favorite) at miles 1, 2, 4 and 5, and a short break at the midpoint for water and food (Allen Lim’s rice cakes). As much as possible, I was trying to simulate the Swim to Moon event, which is an out and back through a series of 3 lakes with aid stations every mile, and the option to pick up your “special needs” bag (food, beverage, etc) at the 5K turnaround.
– Similarities: Gear (no wetsuit), 10K Distance; Nutrition; Distance between fuel stops; Air and Water temperatures.
– Differences: Elevation- Parker Canyon is 5400′ and Halfmoon Lake is 883′; Start time- Swim to the Moon is 7am EST; Support- none today.

I started the swim at 8:30am – air and water temperatures were roughly the same at 76F, with very little wind. There were only a few boats and I was the only person swimming (not unusual for this lake on a Friday). For the first 2 miles the water was surprisingly flat, which made for an easy, relaxed warm-up. After 3 miles I returned to the boat dock for water and food. Even with taking gels every mile (I put one on each side of my head under my swim cap), I often get hungry toward the end of a long swim, so I opted for real food. Allen Lim’s rice cakes are a great combination of sweet and savory, and easy to digest. Total time out of the water was about 10 minutes.

When I resumed swimming there was more surface chop – the wind had picked up and it looked like thunder clouds were moving in. The rest of the swim took a lot more effort, both physically and mentally; but once I completed 5 miles, stopping to stretch my arms and take the last gel, I knew I could finish the remaining distance.

According to my Garmin data, which I uploaded to Strava, I swam 6.4 miles in 4 hours and 42 minutes, which included the non-moving time for breaks. Not fast, but it’s my longest swim to date and at least now I feel confident about finishing Swim to the Moon within the allowed 5 hours. Overall, I think my training plan has worked well and I’ve got the nutrition right.

I started training for this event in February, loosely following the Horsetooth Open Water Swim 10K Training Plan. Their 39 week plan calls for swimming 2 to 3 times a week, with a long continuous swim increasing about 1000 yards every 3 weeks. Hopefully, 3 weeks from race day you reached your 10K goal (which is where I am now). I started doing weekly lake swims in March when the water temperature was around 60F, and my long swims were around 3 miles. My weekly distance has varied from 12,000 to 20,000 yards, but I’ve averaged about 16,000 (swimming 4-5 times per week). My practice swims alternate between technique drills, high intensity interval training, and long continuous swims at a comfortable pace. I cross train with running, a little cyling, yoga, and strength and stability exercises I’ve learned from various physical therapists over the years. In hindsight, I wish I had focused more on upper body strength training, but that’s for next time. Barring injury or illness over the few weeks, I should be prepared for the event!

The water was exceptionally calm at the start of my swim.

There’s one buoy on the lake, which is about a half mile from the boat dock.
