This is my favorite running route. =]
It goes from the back gate of PGP, down to Pasir Panjang Road, up the zigzag road (quite gentle up slope), passing NUH, Science, YIH, then climbing the steps to Engine and crossing the overhead bridge, then running down all the way to west coast Seng Siong for an apple and a bottle of Meiji milk. =]
