Clipper Race teams take part in Boxing Day race

Clipper round-the-world teams will take part in one of the world's most famous yacht races starting today, during leg 6 of their mammoth global journey.

Clipper Race teams set off from St Katharine Docks in September

The Rolex Sydney Hobart yacht race covers 628 nautical miles - and if last year's record is to be beaten the winning team must complete the distance in less than one day, 18 hours, 23 minutes and 12 seconds.

Clipper teams set off from London's St Katharine Docks in September and will return there to finish the race. ITV London's Chris Paxton is taking part on board the yacht Switzerland - you can follow his progress here.
