Jenkins, who has already met British Triathlon’s qualification criteria for the London 2012 Olympic Games, was making her season debut.
She said: “Normally it takes me a few races to warm up, so to come out and get a podium performance is brilliant. My winter training has gone well, and ahead of the next race in San Diego I’ll get another block of training in. I will try to keep progressing from this race, looking forward towards the Olympics.”
Jenkins crashed on the bike last year, and finished 33rd. She said: “It’s always a relief to get the first race out of the way. When the all the bike packs came together I was a bit edgy and had memories of falling off again, so I had to hold my nerve and hold my position in the pack.”
She added: “Having qualified (for London 2012), I have the luxury of peaking at one time, I didn’t have to get into the top six for this race so obviously I’m fit, but not 100% yet so, yes, it’s really positive.”
Fellow Welshwoman, Non Stanford, 23, had a breakthrough race to finish 11th, by far the best performance of her career so far. She finished ahead of Olympic Champion, Emma Snowsill and former world champion, Emma Moffatt.
Liz Blatchford was 18th, Vicky Holland 38th and Jodie Stimpson 45th.
In the men’s race Will Clarke and Tim Don were Britain’s top performers in eighth and 11th place respectively. Both athletes are looking to secure the final Olympic slot that is available alongside Alistair and Jonathan Brownlee, who were not racing in Sydney.
Helen Jenkins now holds the number two world ranking, with points from Sydney and September’s Yokohama race being included. The Series will feature another six events before the Grand Final in Auckland in October to decide this year’s world champions. The next round of the ITU World Triathlon Series takes place in San Diego, California, 12-13 May.
