Minda Dentler was born in India and was paralyzed from the hips down from polio. She ended up in an orphanage, was adopted by a family from Spokane, Washington and spent her life with her legs in braces and using crutches.
After moving to New York City, she was introduced to wheelchair racing and eventually triathlon which led to her giving the Ironman World Championship a try in 2012. She missed the bike cutoff time on her handcycle, but came back with a vengeance in 2013 and not only went 14:39:10, she became the only woman in the first 39 years of the event to actually make all of the cutoff times in her handcycle and racing chair to finish the toughest day in sport!
