India, July 7 -- Actor Milind Usha Soman completed a 600km journey from Mumbai to Goa on June 30 - cycling 90km and running 21km each day for five days. Documenting the feat on Instagram, he described the experience as "amazing". Speaking to us, he shares, "It was never a plan or challenge; it was a test for my mind and body." Known for his disciplined approach to health and fitness, Milind looks at such endurance efforts as "personal fitness checks. "It's something I do once or twice a year," he says, adding, "It could be for a few days, but I surely do something that is fun and full of new learnings." This was not his first time attempting such a venture. The 59-year-old recalls, "I tried my hand at something similar almost a decade ago. I was 50 and it was just cycling to Goa. So this time, I decided to take it further (with running). It looks like a physical challenge, but it is actually a mental one." Ask about the dos and don'ts of taking on such physically demanding routines and he keeps its simple: "I listen to my body and mind before taking up any new physical challenge. You should question yourself and, then it's time to change." For Milind, success lies not in competition but in completion and sustainability, be it a half marathon in Norway or trekking to Kedarnath (Uttarakhand). The actor and fitness enthusiast explains, "For me, my biggest achievement is not winning trophies - it's to not get any sports injury in life. Hence, I approach everything gradually. I have never slogged in the gym or hours. I do 10-15 minutes of different combinations of exercises, whatever my mind says."...
