The towering inflatable was surrounded by cardboard pink lady cut-outs for the Breast Cancer Fundraiser Family Fun Day in the Park.

Volunteers from the Lions Club of Bendigo cooked up a storm while families checked out an array of vintage cars on display in the car park.

Children made the most of the life-size Checkers and Snakes and Ladders games while a brave few had their hair coloured pink.

The event was a fundraiser for Karen Colliver, from Heathcote, and Maree West, from Junortoun.

The women have both battled the ugly beast that is breast cancer and jumped at the chance to take part in Steps for Support: BCNA's Great Wall Challenge in October.

The Breast Cancer Network Australia fundraiser will see participants walk different sections of the Great Wall of China over the course of five days.

Money raised will go towards helping BCNA provide free programs, resources and support for Australians affected by breast cancer.

Participants must raise $3500 each to take part in the challenge.

Ms Colliver and Ms West are still counting the money raised from Sunday's event but thanked the community for its support.

Mandy Hughes from Lockwood South watched on as with Zack, 7, and Taylah, 10, played Checkers.

"It's a good family day out," Ms Hughes said.

"It's a nice day, good weather, and it's for a good cause.

"I had an aunt who had breast cancer - everyone knows someone with it."

Ms Colliver and Ms West are planning more fundraising events for later in the year.

 Ms Colliver said she had received an email about the Steps for Support: BCNA's Great Wall Challenge and instantly decided she had to do it.

"There were only limited places so we'd paid the deposit, put the forms in and had everything done in two hours," she said.
