What inspired you to do this swim?
I did this swim once before. In 2007, my dad and I swam this same course but later in the summer. I decided to do it again because I recently learned that MSF will certify documented swims of choice and I wanted to have the first documented swim of this lake in Minnesota. I chose to swim early in the summer to have colder water. With so many fabulous lakes in Minnesota I think it would be great to get more recognized as marathon swimming opportunities.
How did you plan for the swim?
The planning for this swim was fairly straight forward. Since I was aiming for a specific water temp range of 60-65 degrees, I chose to pinpoint 2 weekends that were likely to be within that range. I lined up accommodations, escort boat, observer and crew for each weekend. Then we watched the weather and water temp closely. We cancelled the first weekend. By the second weekend, all variables lined up and we were set!
How did the swim go, generally? Did you face any unanticipated challenges?
We were pleased with how it went. The wind was strong and slightly at a cross to our course, so our fabulous pilot worked hard to keep our course. Our planning paid off and the feedings and logistics went smoothly.
