London 2012 Olympic medallists the Brownlee brothers will be returning to the venue of their triumph tomorrow 2014 ITU World Triathlon Series hits Hyde Park.
Alistair and Jonathan, who came away with gold and bronze respectively, will be hoping the home crowd can inspire them to more success in the capital.
The world’s best triathletes will be on show in what is the fourth event of the series with the men's and women's elite races taking place back-to-back from 2.30pm and are free to watch.
In addition to the elite races, more than 5000 amateur athletes will have the opportunity to race and an elite international para-triathlon event will take place as the sport prepares for its Paralympic debut in Rio in 2016.
The elite men’s race will feature the three medalists from London 2012, with Spain’s Javier Gomez currently holding pole position in the ITU World Triathlon Series rankings. The Brownlee brothers will want to upset Gomez’s winning streak, but there are other strong challengers that have emerged this season.
Alistair said: "Hyde Park has special memories for me and if we can attract anything like the sorts of crowds we've seen previously then it’s going to be a fantastic spectacle with two sprint races back to back on one afternoon.”
Britain’s Jodie Stimpson sits at the top of the women’s world rankings despite a foot injury in the previous round in Yokohama, Japan, which required five stitches. while Helen Jenkins lies third.
Jenkins said: “I've been really pleased with how this year has gone so far and I’m just really pleased to be able to train and race.
"My training isn't geared to sprint races particularly, but my plan is to enjoy this one with the home support and see what happens."
London has hosted a major international triathlon every year since 2009 and it is hoped that 50,000 people will be attracted to the event.
Mayor of London, Boris Johnson, said: “I am delighted to welcome thousands of the world’s best triathletes for this thrilling sporting spectacular.
"The triathlon continues the legacy of the 2012 Games in bringing top flight international events here benefiting our economy as well as promoting the capital around the globe.”
Spectators are invited to watch the elite events at 8am (international para-triathlon), 2.30pm (elite women) and 4.05pm (elite men) within Hyde Park.
