We were so excited to be riding on tarmac from Swakopmund that we cycled our longest ever day – 141km – from sea level up to 1300m. We’ve been riding (into headwinds of course) on the Trans-Kalahari Highway, past Rio Tinto’s Rossing mine – the world’s largest open-cast uranium mine. Traffic is fairly light, which is lucky as there is no hard shoulder and a speed limit of 120km/hr, and the many trucks are giving us a wide bearth. We’ve seen loads of warthogs and some magnificent kudu as well as oryx and jackals. It’s much hotter now we’re further north and it’s the end of winter – over 30 degrees every day.
