Event description

The Two Continents Adventure Piste is one of the longest and most audacious self-supported cycling events on the planet — a 4,023-kilometre gravel and piste crossing from Irun in northern Spain to sub-Saharan Africa via Morocco, accumulating 52,427 metres of elevation gain along the way. The route crosses the entire Iberian Peninsula on the Iberica Traversa Gravel course, crosses the Strait of Gibraltar to Morocco, traverses the full length of Morocco on the gravel and piste variant of the Morocco Bike Adventure, and continues south beyond Marrakesh toward the edge of the Sahara. It is emphatically not a race in the traditional sense — it is an expedition on a bicycle, planned and executed as such. The logistics require genuine expedition-level planning: border crossings, currency changes, language shifts from Spanish to Darija Arabic and Tamazight Berber, and a transition from European infrastructure to the remote southern pistes of the High Atlas and Anti-Atlas mountains. The 52,427 metres of total climbing is among the highest of any known ultra-cycling route. Riders must understand their own limits with an unusual degree of honesty, as rescue and support become progressively more complex the further south the route goes. The event was designed by Andy Buchs of Transbike Adventures and represents the outer limit of what those events have been building toward.
