A running bug bit Prasun Sikdar, MD and CEO of ManipalCigna Health Insurance Company in 2015, and since then he has run 18 marathons — one full, three ultra and 14 half. “I fall in love with this sport deeper every day,” he says. With his Garmin watch, heart-rate monitor and running shoes, Sikdar dashes against the wind four days a week at 5 am in his neighbourhood. On Sundays, he goes for a long-distance run without fail, all the way from NCPA to Siddhivinayak Temple and back, in Mumbai.
