Anton is an American ultra-runner. He has won the Leadville 100 twice, the Rocky Raccoon 100 Miler, the Miwok 100K, and many other races. Anton is known for his long hair and beard and his minimalist approach, where he often runs with no shirt, short shorts, and with very lightweight running shoes. He ran his first marathon when he was twelve years old, and during college and his early 20s, he often ran upwards of 200 miles a week.
