Last year Ruth Croft won the Tarawera Ultra Marathon, the first person - man or woman - across the line.
This made her the first woman ever to claim the outright title. And if 102 kilometres wasn't enough, this year she went to California and won the female title in the 2022 Western States 100 MILE race - that's 161 kilometres.
Ruth talks to Jesse about getting started in the extreme sport and becoming so good at it.
