THOUSANDS of women are expected to break records when they enter the Race for Life in Huddersfield in June.
The event in Greenhead Park over the weekend of June 16 and 17 is set to be the biggest yet.
Organisers hope that the 7,500 women expected to line up at the start of the three runs will raise an exceptional £350,000 for charity.
Some 5,000 runners lined up last year and both races were subscribed to the full.
Now a third race has been added and there is again expected to be great interest.
There is one race on June 16, at 2pm, and two on June 17, at 10.30am and 2.30pm.
Across the UK more than 800,000 women are expected to come together to take part in Cancer Research UK's world record-breaking Race for Life 2007 series.
The event, supported by Tesco, opens for entries today, and is set to be the largest series ever.
The Race for Life, with 280 events at venues across the UK, hopes to contribute £60m to the charity's scientific work.
Sarah Maddem, the organiser of Huddersfield Race for Life, said: "Last year's event had an unforgettable atmosphere and was a great success, raising £320,000.
"I'd urge every woman to take part. It's such an inspiring day and the money raised makes an invaluable contribution to beating cancer."
Since Race for Life began in 1994 more than 2.7m women across the UK have taken part.
They have raised more than £140m to pay for the charity's pioneering work to help beat cancer.
Every pound raised in sponsorship goes directly to the scientists, doctors and nurses who work to find new treatments.
Last year Cancer Research UK proudly set two Guinness World Records.
They were the `most participants in a multi-location five-kilometre race' and the `most participants stretching simultaneously'.
The latter involved 115,000 women at 24 venues across the UK.
Some women who take part are cancer survivors while others run or walk in memory or to celebrate the lives of family, friends or loved ones, making the race experience both emotional and inspiring.
Gloria Hunniford, patron of Race for Life, said: "Last year we broke two Guinness World Records, thanks to the hundreds of thousands of amazing women who took part.
" This year we want to build on this success and raise even more funds for vital research into cancer.
"The genuine enthusiasm and emotion demonstrated by women across the country creates an atmosphere on race day that is truly inspiring.
"We know the Race for Life holds a special place in many women's hearts and hope that together we will beat cancer."
The series of events begins on May 2 and runs to the end of July.
