The world spins in its axis at roughly 1,000 miles an hour, and it makes one complete revolution around the sun in roughly 365 days. Theorethically, if you wanted to live in a sunny environment 'til eternity, you would have to travel continually at, yes! you guessed it, 1,000 miles an hour.

1) It depends a little on the latitude. Roughly calculated, you would have to go once a day around the world at the equator. This is 40,000 km in 24 hours, so 1,667 km/h. Notice that if you come nearer to the pole, and travel on a parallel, the length of the circle will be always smaller. 2) "A polar circle is either the Arctic Circle or the Antarctic Circle. On earth, the Arctic Circle is located at a latitude of 66Ëš 33' 38" N, and the Antarctic Circle is located at a latitude of 66Ëš 33' 38" S. Areas between each polar circle and its associated pole (north pole, or south pole), known geographically as the frigid zones, will annually experience at least one 24 hour period when the sun is continuously above the horizon and at least one 24 hour period when the sun is continuously below the horizon."

Inside the polar circle, it will be easier and as you approach the pole, you won't have much to move. Provided it is the right season: http://en.wikipedia.org/wiki/Midnight_sun

I believe both previous answers to be incorrect simply because you are able to fly in a plane faster than the sun relative to us. Flying to <a href="http://www.travels.com/destinations/australia-new-zealand/" title="australia" style="", class="stronglinks" target="_blank" />australia</a>, you can arrive before you left in relative local time, and planes do not travel at 1000 km/h. Therefore depending on your path of travel I would say that you'd only have to be moving a little slower than a plane.
