It’s customary for the country that will host the Olympic games to send the Olympic flame on a vast relay.
The flame is passed from person to person, travelling around the country, often accompanied by cheering crowds watching the runners along the route.
For the Sochi Winter Olympics in 2014, the torch is on a journey like no other.
It has moved by runner, troika, reindeer sleigh, dragon boat, go kart, snowmobile, skier, snowboarder, ice-swimmer, speed skater and even on a Russian nuclear-powered icebreaker (ship).
