With Theresa Wallach, she crossed the Sahara by 600cc Panther motorcycle, sidecar and trailer from London to Cape Town in 1934–35, making the return journey on her own in 1935–36.

[1] Blenkiron was interested in visiting family friends in Cape Town and after a joking conversation about getting there by motorcycle, the two women started to plan a trip in earnest.

Other sponsors then emerged, including the provision of the trailer and sidecar by Watsonian Squire, and Blenkiron proceeded to stress test the equipment at various events in 1934.

[8] She was elected as an Associate Member of the Women's Engineering Society in 1938[9] in recognition of the journey to Cape Town and back, along with her considerable experience of the administrative side of steel production whilst working for the foundry firm Hadfields Ltd.[10] In 1937 Blenkiron began to advertise her services as a chauffeur and tour guide.

She placed an advert in The Woman Engineer journal for "Valet Motoring Go wherever you will, not where you must Private Tours at home and abroad arranged exclusively to please you and your friends Miss Florence Blenkiron experienced courier, with own 18 h.p.

She hopes to be allowed to do her "bit" without further delay" and by autumn 1940 it was able to share that "Miss Florence Blenkiron A.T.S...is to sail shortly for Kenya with the Mechanised Transport Corps.".

[12] Blenkiron wrote to the Women's Engineering Society from Pretoria in the summer of 1941 that "we are housed in most comfortable huts in the military quarters and have helped the transport workers generally, driving cars, six wheeled lorries etc... it is awfully difficult to know just how much one may say in a letter so I think perhaps I should wait until I can relate my experiences at the end of the war" and that she had just received marching orders to go north.

She was also responsible for teaching a driving and maintenance course for all United Nations Relief and Rehabilitation Administration personnel sent on service to Egypt, which they had to pass before being allowed access to military vehicles.

[13] In 1945 Blenkiron was mentioned in Despatches and in charge of 30 buses driven by Palestinian women in Cairo for the transportation of Army Officers between their place of residence and Headquarters.

Florence returned to Britain for a month arriving at Tilbury on 3 November 1947 on the ship Strathmore and leaving Liverpool for Bombay on the Empress of India in December 1947.

Once the club closed and Kenneth was demobbed from the army, he worked for an American pharmaceutical and Florence project managed the restoration of a factory for his company, before they returned to Britain in 1955.

In 2018, a collection of previously unknown 66 Ilford Special Lantern Plate glass slides (8.3 cm x 8.3 cm) in a Union Jack patterned box, showing the 'Venture' Panther motorcycle and sidecar, and scenes and countryside along the route of Florence and Theresa's journey from London to Cape Town were sold by auction at Toovey's Auction House[15] in West Sussex.
