The 15-day trek and 600-mile journey from Port Elizabeth to Durban was accomplished using a fleet of Defenders, Discovery and Discovery Sports towing 1.5 tonne boats and traversing rather nasty terrain.
Navigating rugged costal roads around the eastern coast of South Africa, ten Land Rover support vehicles carried the expedition kit and two boats, enabling the team to enter the water along the coast and track marine life.
The expedition took genetic samples from sharks which will be used in ecology studies for South Africa Shark Conservancy.
Monty Halls commented 'The Sardine Run is a truly iconic event amongst naturalists, divers, and adventurers. The biomass of the shoals, along with the attendant predators that follow in their wake, matches the Serengeti which hosts the largest terrestrial mammal migration on earth.
'To seek out these vast aggregations of sardines as they work their way up the eastern coast of South Africa has been one of my lifetime ambitions, and the reality certainly matched the many years of expectation.
'To track the sardines we used a fleet of Land Rovers, transporting kit and towing boats for 1000 kilometres (600 miles) along the most challenging, stark and beautiful coastal landscape I have ever seen.
'Launching the boats alone was a monumental challenge, but once we had negotiated narrow river inlets and huge surf, we were in another world. The expedition encountered breaching humpback whales, vast flocks of Cape Gannets, cruising sharks, and - most memorably of all - a super pod of four thousand common dolphins racing along the shoreline seeking out the sardines. A great expedition, a great team, a magnificent spectacle - the memories will last a lifetime.'
