By speed · Order from slowest to fastest.

  1. A koala on the run 30 km/h

    Koalas sleep up to 22 hours a day because their eucalyptus diet is so low in energy and mildly toxic.

  2. A running reindeer 80 km/h

    Reindeer eyes change colour with the seasons, turning blue in winter to see better in the dim Arctic light.

  3. A luge slider 140 km/h

    Luge athletes steer a tiny sled with subtle leg and shoulder pressure while lying on their backs, feet first.

  4. A downhill speed skier 255 km/h

    Speed skiers tuck into an egg shape and wear airfoil helmets, accelerating faster than a free-falling skydiver.

  5. A Category 5 hurricane's winds 300 km/h

    A single mature hurricane can release more energy in a day than the world uses in electricity all year.

  6. A Boeing 747 cruising 920 km/h

    The 747's hump exists because the cockpit was put on an upper deck so the nose could hinge open for cargo.
