The core team of 10 left Cornwall on 10 August to start the 874-mile challenge and are being joined en route by more than 40 others. They are expected to arrive on Saturday (29 August).
Globally, similar events are planned to achieve a cumulative 30,000km total – equal to circumnavigating Africa.
Ride4Rangers is a collaboration with conservation charity Tusk. In other events, a team in South Africa’s Kruger National Park are doing a relay walk from north to south, while in northern Kenya, another team are doing a horse ride for rangers traversing the Borana conservancy and into Lewa conservancy.
