TWO of the capital's best-known luminaries have joined together to promote the Mother's Day Classic fun run.

Chief Minister Katy Gallagher and WIN TV presenter Danielle Post will both be running in the 10-kilometre section of the charity event, raising money for breast cancer research.

Ms Gallagher is making up for a busy election year that limited time for running by completing her second event in a month, and is hoping to break the one-hour mark.

''I did 1.01 in the Canberra Times [10-kilometre run],'' she said. ''I'm fairly confident I'll crack the hour.''

The mother of three said running was her stress release.

''It is the only time I find that I don't have someone in my ear, either child or work,'' she said.

''And it allows for that clarity - I often come back from a run with a long list of things to do.''

Nightly news anchor Ms Post said her running for charity began four years ago with a half-marathon, after her grandmother was diagnosed with breast cancer.

''My grandma's had breast cancer twice, and so when she was diagnosed at age 89 I decided to raise money for breast cancer research,'' she said.

''This is the biggest run I've done in Canberra.''

Organisers are hoping that 6000 Canberrans will take part in the 5km or 10km walk or run around Lake Burley Griffin on May 12.
