Fitness is key at Malaysian GP

High temperatures, monsoons, high-speed corners all play their part in the next round of the F1 World Championship in Malaysia.

Last year's GP ended in controversy as the rain came down, turning up the circuit into a lake and forcing the FIA to halt the race early. Bernie Ecclestone got some flak for scheduling the race for a more favourable European TV viewing time while ignoring what everyobdy in Malaysia knew - that it rains hard in the late afternoon during the Monsoon season.

Whether or not such problems face the drivers this weekend remains to be seen but they will have to cop with the heat and high-speed corners that sap the energy. Williams Niko Hulkenberg reveals more.
