J Scott Chapman is a certified ultrarunning coach who really enjoys big mountain races. Given that two of his core values are curiosity and exploration, he loves to read the latest studies, but he knows that ultras are not run in a lab. His coaching philosophy embraces the idea that while there are established training principles, no single approach fits everyone. He considers each individual's unique life circumstances to create the best plan, understanding the need for tradeoffs to ensure the training aligns with their lifestyle and goals.
