Challenge Samarkand is a middle-distance race in the heart of the Silk Road. A flat swim, fast open-road bike and a run past UNESCO-listed monuments make it one of the most distinctive races on the Challenge calendar.
1.9 km single-loop swim in a calm inland reservoir on the edge of the city; typically warm and flat with little current.
90 km out-and-back on open, wide roads through the plains around Samarkand; mostly flat to gently rolling with exposed sections where wind is the main resistance.
21.1 km flat run past the Registan and the historic Silk Road monuments in the city centre - dry heat and stunning scenery.

Water temp uses athlete-reported values first, then official race data, then the marine archive (sea swims, measured at the nearest offshore point). Values tagged est. are modelled from recent air temperature for lakes and rivers, where no observational data exists.
