Dipa Karmakar, who blazed a trail by becoming the first Indian woman gymnast to compete at the Olympics and finish a historic fourth, announced her retirement on Monday, ending a career in which she inspired awe for routinely performing the highly-difficult Produnova vault. The diminutive 31-year-old from Tripura grabbed headlines with her fourth-place finish in the vault final of the 2016 Rio Games, losing an Olympic medal by just 0.15 points. "After much thought and reflection, I have decided to retire from competitive gymnastics. This is not an easy decision, but it feels like the right time," she said in a statement.
