This panoramic photo below was taken outside the then South Fremantle Post Office on Hampton St (the building is still there and still in use). The angle of the sun puts the time around mid afternoon, so perhaps these are the finishers gathered for a group photo.

The race was held on Saturday Spetember 6th 1931, the same day as the Northam to Perth and a week before the Beverley to Perth. It was won by L. McGuckin who, according to the article in The West Australian the following Monday, "has not ridden for some years"
