In preparation for our upcoming swims, my friend Bill Daugherty and I decided we would do our longest training swim yet at Patagonia Lake on Friday, May 12. Bill will be swimming in the El Cruce 10k Open Water Swim in Cancun, Mexico on May 27. I’ll be doing The Great Chesapeake Bay 4.4 Mile Swim on June 11. Bill is a great swim buddy and inspiration! He did the Chesapeake Bay last year at the age of 73! Bill planned to swim 6 miles, and I was planning to do 5. Two weeks before, we had both swam around 4 miles.
Last month, I measured our course with my old Garmin Forerunner 305 inside a swim buoy that I pulled behind me. Starting from the beach at Patagonia Lake, the course is a counter-clockwise loop, which my Garmin measured as around 1 mile. That closely matched the same course plotted on Google Earth shown below. However, another athlete joined us for the swim on Friday and her Garmin (worn on her wrist) measured the same loop course as 1.38 miles. I’d like to believe that, but I’d rather be conservative when it comes to training. In any event, we swam 5 loops of this course, with quick stops for water and gels.
