The trouble with rocket-powered roller skates is that you can’t steer.

To remain on land as long as possible, we suggest you start in northern Siberia (99°1’30E 76°13’6N) and point yourself due south. That’ll take you through 4,717 miles of Russia, Mongolia, China, Burma, and Thailand before you splash into the South China Sea.

Or start at 48°24’53N 4°47’44W in northern France and head east. An unswerving course will take you through Europe, Ukraine, Russia, Kazakhstan, Mongolia, China, and Russia, covering 6,665 miles before you hit the Sea of Okhotsk. Good luck.
