The event, the last of the five-race British Triathlon Super Series, also constitutes the finale to the GE Great Britain triathlon team’s season following the athletes’ return from the Dextro Energy Triathlon ITU Triathlon World Championship Grand Final in Budapest, where Alistair won the senior race and Jonathan lifted the under-23 world crown.

Big names such as the Brownlee brothers, Olly Freeman and Will Clarke feature on the start list for Blaenau Gwent event while there will also be local interest in Welsh athlete Luke Watson, who will be looking to impress at his home race.

Within the 50 British senior names, eight of the final top 10 from the 2009 British Triathlon Super Series will be participating, including Stuart Hayes, Aaron Harris and Phil Wolfe who finished first, second and third respectively. 

Jonathan Brownlee, who this season has also won 2010 ITU Elite Sprint Triathlon World Championship, admittedhe is keen to finish his season on a high as he races for the first time in the Welsh valleys at Parc Bryn Bach.

The 20-year-old star, who is one of Britain’s top London 2012 medal prospects, said: "This year has been a real breakthrough year for me and I want to finish the season with a win.

"It will be great to race at Parc Bryn Bach as I haven’t competed there before and I’ve heard it’s a challenging course."

In the women’s event, which takes place on the same day as the men’s race, notable names taking part include Helen Jenkins, Kerry Lang, Jacqueline Slack and Jodie Stimpson, with the latter two sitting in first and second position respectively in the 2010 Super Series rankings.

Along with Jenkins, the Welsh contingent also consists of Non Stanford, who placed second in the 2009 Super Series, and Carol Bridge.

Jenkins, who recently won the fourth Super Series event at the Challenger World London Triathlon, said: "I can’t wait to get out on the challenging course Parc Bryn Bach offers and prove myself on home ground.

"I’ve had a great season so far and aim to make the podium next Sunday, hopefully with lots of local support."

Heather Williams, Performance Director at British Triathlon, added: "We are obviously pleased to have the level of field which we have for this final Super Series event.

"Having staged events at Parc Bryn Bach in previous years, we know the course will provide a good test for all the athletes taking part in the race."

Alongside the Super Series, the British Triathlon Inter Regional Championships (Tri Star 2, Tri Star 3 and Youth categories) have been incorporated and will showcase some of the best young triathlon talent the UK has to offer. 

Also included in an action packed race schedule are the British Elite Triathlon Championships, and the finale of the 2010 British Triathlon Youth and Junior Super Series featuring children as young as 11-years-old.
