Gunn Runners has a healthy social group that meet regularly outside of Tuesday night's run for social activities.

The Social group is moderated by the Gunn Runners President (info@gunnrunners.org.au) and administered by Google Groups.  You need to create an account with Google, sign-in and allow your account to receive emails posted to the group.
