This man is trying to become the first person to ever cycle solo and unsupported across Antarctica to the South Pole. His main coach is Chat GPT. His name is James Benson King and he's going to ride alone across the ice for up to two months, dragging everything he needs to survive through temperatures below minus 40 degrees. Normally, preparing for this means hiring separate coaches for endurance, strength, technical skill and cold weather survival. Instead, James built his own training system, folding every discipline into one flexible plan. And this isn't just a YOLO, he tested the Icelandic highlands when his stove broke in the cold, he described the problem and worked through a fix on the spot. He used it to design workouts from whatever gear he had and to make weight saving calls. He even cut his toothbrush in half. He says it rarely gives him a definitive answer, but it helps him ask the right questions.
