   Even Effort, No Hills

   With only 40 m of total climb on a flat profile, there are no hills to save for. Run even splits from the gun rather than banking energy for climbs.

   Know Your Loop

   The course is one loop through the Palermo parks, Recoleta, the Obelisco, San Telmo and La Boca, so each neighborhood comes once. Note the order and pace yourself to still run strong in the later ones.

In Buenos Aires

• Getting Around

  The Subte and city buses cover the center and Palermo well; with race-day road closures around the course, underground travel is usually the simpler option.

• After the Finish

  Porteños eat late and linger over coffee, so a slow afternoon in Palermo's parks or the streets of San Telmo suits the city's pace while your legs recover.
