"There's such a long way to go," he told reporters. "We've got a lot of competition out there so I'm sure everyone's going to be pushing and so we need to stay on it. We've got to keep pushing.
"I don't think any race is easy. Obviously there are opportunities that are presented in front of you and you have to take them with both hands and that's what I did but looking after the car, looking after fuel, not making any mistakes, it was a massive challenge in that sense.
"The steps we've taken through the winter from the end of last year to this year, and now to have a one-two, is absolutely incredible. I've not had many one-twos in my career so that makes it even more special."
Hamilton's teammate Nico Rosberg currently leads the standings with 43 points.
