Kuala Lumpur:With a huge Indian population in Kuala Lumpur and plenty of fans flying down from Chennai, Narain Karthikeyan is gearing up for the Malaysian Grand Prix to be held at the Sepang racetrack. The fastest Indian on wheels will be looking to go one better than the 15th place finish he had at Melbourne Grand Prix. Karthikeyan is eagerly looking forward to the start of the race even though the tropical weather conditions will be more demanding than in Melbourne. Karthikeyan in fact flew directly from Australia to Malaysia to give himself time to acclimatize. "Trainer Gerard and me have been training outdoors for body to acclimatise to heat. We are doing a lot of cardio, neck and shoulder exercises. I have been exercising four hours a day and so hopefully on Sunday I will find the race easy. But even for those who have been in F-1 for a long time this is one of the hardest venues," said Karthikeyan. The temperature in fact rose to 55 degrees Celsius on Friday as Karthikeyan took to the track for a practice session. The 28-year-old finished 19th in practice on Friday at Sepang, three places behind reigning world champion Michael Schumacher. Tough one Having taken to the track, Narain considers this a tough one for rookies. "It will be a lot of fun to drive as there are lot of flowing corners. The only thing is that heat and humidity will be very tiring," said Helping Karthikeyan get over his nervousness will be Malaysia's sizeable population of Indians and Formula one fans from India visiting Sepang for Sunday's race. "It's a nice warm atmosphere here. Lots of fans in shopping malls and wherever I have been. I expect a lot of support here. Race is close to home, so I have a special feeling for it," he added. Karthikeyan debuted in Melbourne as the best rookie of the season. And according to the 28-year-old, keeping the momentum going and learning from experience is the best way forward for the future.
