This Sunday, over 600 participants are set to participate in a unique race where the rules of engagement run backwards. In an attempt to create a new Guinness World Record for the largest number of people running a backwards race, a beverage brand launched earlier this month will organise the race at Powai's Hiranandani Gardens, on May 28.
