Hyderabad industrialist Krishna Prasad celebrated his 60th birthday by running 7 half marathons on 7 continents in 7 days. He was partnered in the feat by his wife Uma Chigurupati, 53, and the couple now have a place in the Guinness Book of Records, for the third time in a row. Wife Uma said at first she dismissed the idea as absurd as Prasad wanted to run full marathons, so he agreed to make them half marathons as a concession to convince Uma as the couple has always run together. They first started running some 12 years ago in Hyderabad then went on to Antarctica and the North Pole, then on to France. This time they knew this run was going to be tough, but the couple were determined and enjoy running together, and they did it!
