Course intel
San Juan, Argentina's full-distance race at the foot of the Andes: from a reservoir at about 960 m the course drops to about 780 m, rolls between 780 and 850 m until 55 km, then eases down to the plain on the edge of the city at about 620 m, where the second half loops between 610 and 700 m. About 540 m of elevation gain, a net descent overall, and thin air at altitude all help speed. Early November is late spring in the southern hemisphere; the desert climate is hot, dry and sunny, so hydration and heat control in the second half are what matter.
