Mary Kom is the only woman to have won the World Amateur Boxing Chamionship a record six times, and the only woman to have won a medal in each of the seven World Championships. Kom won bronze at the 2012 Olympics, and is now dreaming of gold at the 2020 Games, for which she is training hard at the Indira Gandhi Arena in Delhi. Fondly called India’s ‘Iron Lady’, she, too, feels tired on some days, especially after an arduous session of physio, she says.
