In 2000, the small town of Kalpetta held a race. One girl ran an 800-metre race barefoot and with no prior coaching. She completed it with a 100 metres lead. Fifteen years later, O P Jaisha broke the national record at the Mumbai Marathon, topping the previous 19-year-old record. She followed this up with breaking her own record at the World Athletics Championships, Beijing, qualifying for the Rio Olympics in 2016. She believes she can top her own record again. Yet, there are many odds stacked against her.
