Britain's Alistair Brownlee is favourite to secure the world title at the series grand final in Australia this weekend but 12 other men could still overhaul him.

In the women's series, Emma Moffatt leads the pack, with Brit Helen Jenkins an outside shot to retain the title she won under the old format last year.

Watch highlights from both final races on Sunday on BBC Two and the BBC Sport website (UK only) 1600-1730 BST.
