In all positive aspects of the word, Fred has become The Big Swim's resident curmudgeon at large. (Fred open your mouth more!)
He asks: Maps look nice but why all the turning?
All 20 of the maps were completed with exactly 0.25-kilometer segments. Using this measurement, the total trip takes 211 kilometers around Jeju. If I do a 1-kilometer segment map around Jeju, the trip total drops to 187 kilometers - the perfect swim. But Sherrin doesn't swim in a straight line. The 0.25-kilometer segment map is more realistic for planning. True, the water is a bit choppier at the shores, but if anything were to happen, we are happy to be closer to the shore than out at sea.
As for the maps, I think of them more as a guideline. The goal is to complete the swim within the allotted 27 days. The guidelines tell us this is possible and can be done safely.
