The 2012 summer Olympic Games takes place in London, England starting next month.

From July 27 to August 12, athletes from 203 countries around the world will converge on the city to compete in sports including swimming, cycling and diving.

Before the competitions begin, the Olympic torch is run in a cross-country relay through more than 1,000 cities in the United Kingdom.

The torch was flown to the UK on May 18 and the huge, cross-country relay began.

In the relay, runners hold the torch aloft as they run and when they get to a certain spot they light the next runner’s torch–and so on.

The last torchbearer will light the giant cauldron in the Olympic Stadium in London, to mark the start of the Olympic Games for 2012.
