Pro tips

  1. 01

    Cool, Early Gun

    The start is at 07:00 with race-day temperatures typically around 13C, so warm up before dawn and expect a chilly first few kilometers before you settle in.

    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.

    Where the Support Is

    The route threads through Palermo parks, Recoleta, the Obelisco, San Telmo and La Boca, so the loudest crowds will be in the central stretch. Plan your surges for those sections.
