Participants threw rugby balls while running around a fountain, completed brain teasers and navigated various sections of the garden.
Those taking part were encouraged to make a donation to the neurosurgery campaign. Personal fitness trainer Rory McSweeney organised the event, as a way to support the community through exercise and generate money and awareness for the neurosurgery appeal.
The event raised $1160 for the Chair in Neurosurgery campaign, which aims to endow an academic who will be a third neurosurgeon at Dunedin Hospital.
The tour included the site of Dunedin's first medical school at the Exchange; the anatomy museum at Otago University; historic doctors' residences; potted histories of Dunedin and Wakari hospitals, and Ashburn Clinic.
