Beijing Winter Olympics-bound Indian skier Arif Khan, who will participate in two events, is aiming a modest top-30 finish in the showpiece which begins on Friday. The 31-year-old Khan is the lone Indian participant in the February 4-20 quadrennial event. He secured his berth in the Winter Olympics in a qualifying event in Dubai last year. "To be honest, if you want to be a medal contender, you require at least 10 years of training and preparation, (need) to have (decent) budget and funding, only then it's possible to be in medal contention," Khan, an Alpine skier, said at a virtual interaction, organised by the Sports Authority of India, on Sunday.
