This octogenarian has just completed her THIRD Tough Mudder, one of the most grueling endurance events in the world. Mildred Wilson, 83, is the oldest person ever to complete the brutal course. Tough Mudder is an endurance race filled with punishing obstacles such as a giant ice bath, a 60-foot watery trench under a steel fence, a dash through 10,000 volts of electricity and a 12-foot wooden ladder with giant rungs named the 'Ladder to Hell'. Mildred, a former vending machine company worker from Sikeston, Missouri, USA, said: “I knew last year I would do another as long as my health was good. “It really didn’t require a decision. Last year when asked if I would do another, my answer was ‘at my age I don’t plan that far ahead but if I am still here and able I definitely will'. “I didn’t really know I was the oldest to do a Tough Mudder until this year. It’s kind of an honor and everyone makes me feel special.” On May 1, Mildred trudged through mud and obstacle courses for two and a half hours to complete her third race. Dubbed “Muddy Mildred,” Mildred completed her first obstacle course shortly after her 80th birthday in 2019 after her son Danny, 48 and an active Tough Mudder, asked her if she wanted to do a local one. While the run was paused in 2020 due to COVID-19, Mildred conquered the course for the second time when it returned on May 9, 2021. Though she’s completed two other runs in the past, Mildred said this one was harder. Though she never plans that far ahead, Mildred hopes to complete another course next year. She said: “Definitely yes I want to and to do another Tough Mudder next year if God continues to bless me with good health.” *Video filmed in 2021.
