World Record holder Paula Ratcliffe in action
Paula Radcliffe MBE is to be a patron of the charity, Jane Tomlinson Appeal, and will run the Leeds 10K on July 4 2010.
The British long-distance runner is world record holder for marathon, 20K and 10K road runs.
Jane Tomlinson Appeal was established by the late fundraiser to raise funds for children's and cancer charities.
Jane and her family set up the Leeds 10K, now in its fourth year, to stand as her fundraising legacy.
Paula, 36, said: "It is a huge honour for me to be a patron of Jane Tomlinson Appeal. Jane was such a very special person. Her bravery, courage and strength were a huge inspiration to me and I am sure to so many others. She fought cancer every step with such passion and positivity."
"Through her appeal that fight lives on and the chance to take part in the Leeds race means a huge amount to me not only to remember and celebrate her, but also to do what we can to continue the work she started in raising as much as we can to help fight cancer."
This year the Leeds 10K will also be televised for Channel Five and will be the focus of a special hour-long programme on Saturday 10 July 2010.
In 2002, both Paula and Jane ran their first London marathon. Later that year the two met for the first time when Paula presented Jane with her award at the BBC Sports Personality of the Year.
Before her death from breast cancer in 2007 Jane raised £1.85m through a series of physical challenges. Her family, led by husband Mike, is determined to continue the work she began and to date, more than £3m has been raised by the Jane Tomlinson Appeal.
11,000 people are expected to join the Leeds 10K. More information is available on the
