When Coach Davis said this to him, Jake agreed that he needed more difficult training, he had realized how good this training could be for him, and he also knew he could do more than that.
After Jake had become accustomed to swimming in the sea, these trials were no more difficult for him, he also enjoyed a challenge and thought it might be better for him to make more training gains.
Seeing that Jake had agreed to increase the difficulty of training, Coach Davis greatly increased the training load, swimming was 1 km at sea, cycling was 25 km and running in the sand 15 km.
Coach Davis trained to be harder for Jake instead of being more evenly balanced to compete in the triathlon that was not the goal of this training, running was the easiest for Jake who normally ran 50 km at a pace to break the world record every day.
