This is the fourth year Susan Dixon has been taking part in the Cancer Council fundraising event but this time it will look a little different.

Normally, she would make her way down to Sydney for the massive event which sees thousands of participants walk 28 kilometres from Milsons Point across the Sydney Harbour Bridge, Pyrmont Bridge, ANZAC Bridge, Gladesville Bridge and back to the lower North Shore.

This year, the event has gone virtual and is encouraging participants to walk the distance in their own neighbourhood, at their own pace.

And that's exactly what Susan has planned for Sunday, October 25, with a couple of friends in tow.

Despite having the option to walk or run the full distance over seven days, Susan, along with Gayle Hollingsworth, Hildegard Griffin and Marika Hollingworth will undertake it all in one day.

"We've worked out a route," Susan explained. "We're combining one long leg (20kms) with a shorter walk through Gloucester District Park to the Meadows and back."

For Susan, it's an important event to continually take part in, helping raise money for the Cancer Council and its research.

"I'd like the treatments to be pretty good by the time I need it," Susan explained.

She has cancer in her family, having lost both her parents to it and a sister who continues with ongoing battles.

"The walk is a bonus. It keeps you fit and my dog benefits."

Susan and Gayle have been walking most Saturday mornings in preparation for the event and they view this walk as a team effort, setting up on fundraising page to cover them all.

The team will be kicking off at 7am for the long walk which is expected to last them until 10am when they will have a break before taking on the final distance.

"If anyone wants to join us for the short walk we'll be meeting out front Bi-Rite (corner of King and Church) at 11am," Susan said.
