Giving back to the community
As part of Discovery Day, we’re delighted to be partnering with two local charities, West Welcome Wagon and Community Bike Hub.
The run registration fees will raise funds for these organisations.
Both charities play a big part in building community belonging and connection, and these proceeds will help each organisation continue their important work to serve the diverse people, communities and places of Melbourne’s west.
