Jonny Brownlee will hope to cap a brilliant year for his family by following in the footsteps of brother Alistair and being crowned world champion in New Zealand this weekend.
The pair became the first British athletes to win Olympic medals in triathlon in Hyde Park this summer when Alistair took gold and his brother bronze.
Alistair has dominated the sport over the past three years, including holding off the challenge of Jonny to win his second world title 12 months ago.
But his hopes of defending his title were ended by an Achilles injury suffered earlier this year and instead it is Jonny who has taken over the mantle.
The 22-year-old from Leeds heads into the World Triathlon Series Grand Final in Auckland with a 180-point lead over Spain's Javier Gomez, the Olympic silver medallist, and knowing a podium finish will be enough to secure the title.
The hilly bike course should suit Jonny, who has won races in San Diego, Madrid and Stockholm this season, but he knows he will have to be on top of his game.
The Yorkshireman said: "It's an honour to be thought of as the favourite for the title, but there is a job to be done this weekend and I am not underestimating the competition or the conditions.
"This is going to be a tough race on a challenging course against athletes who all want to end their seasons on a high.
"Whatever happens on Sunday I have had a fantastic year. To finish it off with the world title would really be something special, but I know I have to stay focused in the lead-up and get everything right if that is going to happen."
