A test of the Olympic torch run is underway Friday from Leicester to Peterborough in eastern England.

London Olympic officials are conducting a full dress rehearsal of the run to test timings, traffic and security issues as the convoy moves along.

Some 122 volunteers are running with the torch on Friday, but it won't be lit. The flame only comes when the actual torch relay starts from Land's End in Cornwall next month.

The real Olympic torch relay will take place for 70 days and will involve 8,000 torchbearers. It will travel throughout Britain as well as making a stop in Dublin.

London organizers hope the relay will build excitement ahead of the games, which take place from July 27-Aug. 12.
