Now in its seventh year, Women's Health Week is an initiative of Jean Hailes, a national not-for-profit organisation that is dedicated to improving women's health by providing information, resources and clinical care to help women actively manage their own health and wellbeing.

Branxton personal trainer Katie Miller will host a ladies' picnic at Miller Park this Saturday to raise funds for the Jean Hailes program, and create awareness for the importance of women's health in the local community.

Katie, who runs KFIT Health and Training, has clients aged from their teens to their eighties, many of whom have accessed Jean Hailes' resources.

She says the picnic will have an emphasis on being fun, happy and healthy, and that women of all ages are welcome to attend and share their experiences in a supportive environment.

"There will be conversation starters to talk about women's health, and we'll play some games, all health-related," she said.

"It's going to be a great morning, meeting and interacting with new ladies for an amazing cause."

The event will start at 8am with a half-hour workout, followed by the picnic. Participants are encouraged to bring along a plate of baked goods or snacks to share.

Tickets are $20, which includes a group workout, a coffee and a donation to the Jean Hailes program.

Tickets must be purchased by Friday. For more information, find the Facebook event 'A Ladies Picnic - Womens Health Week', or call Katie on 0432 387 805.
